+ * DMA-BUF/GEM Object references and lifetime overview:
+ *
+ * On the export the dma_buf holds a reference to the exporting GEM
+ * object. It takes this reference in handle_to_fd_ioctl, when it
+ * first calls .prime_export and stores the exporting GEM object in
+ * the dma_buf priv. This reference is released when the dma_buf
+ * object goes away in the driver .release function.
+ *
+ * On the import the importing GEM object holds a reference to the
+ * dma_buf (which in turn holds a ref to the exporting GEM object).
+ * It takes that reference in the fd_to_handle ioctl.
+ * It calls dma_buf_get, creates an attachment to it and stores the
+ * attachment in the GEM object. When this attachment is destroyed
+ * when the imported object is destroyed, we remove the attachment
+ * and drop the reference to the dma_buf.
+ *
+ * Thus the chain of references always flows in one direction
+ * (avoiding loops): importing_gem -> dmabuf -> exporting_gem
+ *
+ * Self-importing: if userspace is using PRIME as a replacement for flink
+ * then it will get a fd->handle request for a GEM object that it created.
+ * Drivers should detect this situation and return back the gem object
+ * from the dma-buf private.

  *	If unsure, don't give this parameter.
  *
- * dslot:
- *	NOTE: only one dslot value must be given for every card.
- *	Also this value must be given for non-E1 cards. If omitted, the E1
- *	card has D-channel on time slot 16, which is default.
- *	If 1..15 or 17..31, an alternate time slot is used for D-channel.
- *	In this case, the application must be able to handle this.
- *	If -1 is given, the D-channel is disabled and all 31 slots can be used
- *	for B-channel. (only for specific applications)
+ * dmask and bmask:
+ *	NOTE: One dmask value must be given for every HFC-E1 card.
+ *	If omitted, the E1 card has D-channel on time slot 16, which is default.
+ *	dmask is a 32 bit mask. The bit must be set for an alternate time slot.
+ *	If multiple bits are set, multiple virtual card fragments are created.
+ *	For each bit set, a bmask value must be given. Each bit on the bmask
+ *	value stands for a B-channel. The bmask may not overlap with dmask or
+ *	with other bmask values for that card.
+ *	Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000
+ *		This will create one fragment with D-channel on slot 1 with
+ *		B-channels on slots 2..15, and a second fragment with D-channel
+ *		on slot 17 with B-channels on slot 18..31. Slot 16 is unused.
+ *	If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will
+ *	not function.
+ *	Example: dmask=0x00000001 bmask=0xfffffffe
+ *		This will create a port with all 31 usable timeslots as
+ *		B-channels.
+ *	If no bits are set on bmask, no B-channel is created for that fragment.
+ *	Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask)
+ *		This will create 31 ports with one D-channel only.

-    This driver supports the bmp085 digital barometric pressure
-    and temperature sensor from Bosch Sensortec. The datasheet
-    is available from their website:
-    http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP085-DS000-05.pdf
-
-    A pressure measurement is issued by reading from pressure0_input.
-    The return value ranges from 30000 to 110000 pascal with a resulution
-    of 1 pascal (0.01 millibar) which enables measurements from 9000m above
-    to 500m below sea level.
-
-    The temperature can be read from temp0_input. Values range from
-    -400 to 850 representing the ambient temperature in degree celsius
-    multiplied by 10.The resolution is 0.1 celsius.
-
-    Because ambient pressure is temperature dependent, a temperature

+ *  and temperature sensors from Bosch Sensortec. The datasheets

+ *  A pressure measurement is issued by reading from pressure0_input.
+ *  The return value ranges from 30000 to 110000 pascal with a resulution
+ *  of 1 pascal (0.01 millibar) which enables measurements from 9000m above
+ *  to 500m below sea level.
+ *
+ *  The temperature can be read from temp0_input. Values range from
+ *  -400 to 850 representing the ambient temperature in degree celsius
+ *  multiplied by 10.The resolution is 0.1 celsius.
+ *
+ *  Because ambient pressure is temperature dependent, a temperature
+ *  measurement will be executed automatically even if the user is reading
+ *  from pressure0_input. This happens if the last temperature measurement

-   - Added code that unregisters irq and proc-info
-   - Version# bump
-
-   Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
-   - pass 'dev' as last parameter of request_irq in stead of 'NULL'
-
-   Wed Feb  7 21:24:00 CET 2001 (Alfred Arnold)
-   - added support for the D-Link DE-320CT
-
-   *    WARNING
-	-------
-	This is alpha-test software.  It is not guaranteed to work. As a
-	matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
-	would like to hear from you if you use this driver, even if it works.
-	If it doesn't work, be sure to send me a mail with the problems !

-    Most of this driver, except for ultramca_probe is nearly
-    verbatim from smc-ultra.c by Donald Becker. The rest is
-    written and copyright 1996 by David Weis, weisd3458@uni.edu
-
-    This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
-
-    This driver uses the cards in the 8390-compatible, shared memory mode.
-    Most of the run-time complexity is handled by the generic code in
-    8390.c.
-
-    This driver enables the shared memory only when doing the actual data
-    transfers to avoid a bug in early version of the card that corrupted
-    data transferred by a AHA1542.
-
-    This driver does not support the programmed-I/O data transfer mode of
-    the EtherEZ.  That support (if available) is smc-ez.c.  Nor does it
-    use the non-8390-compatible "Altego" mode. (No support currently planned.)
-
-    Changelog:
-
-    Paul Gortmaker	 : multiple card support for module users.
-    David Weis		 : Micro Channel-ized it.
-    Tom Sightler	 : Added support for IBM PS/2 Ethernet Adapter/A
-    Christopher Turcksin : Changed MCA-probe so that multiple adapters are
-			   found correctly (Jul 16, 1997)
-    Chris Beauregard	 : Tried to merge the two changes above (Dec 15, 1997)
-    Tom Sightler	 : Fixed minor detection bug caused by above merge
-    Tom Sightler	 : Added support for three more Western Digital
-			   MCA-adapters
-    Tom Sightler	 : Added support for 2.2.x mca_find_unused_adapter
-    Hartmut Schmidt	 : - Modified parameter detection to handle each
-			     card differently depending on a switch-list
-			   - 'card_ver' removed from the adapter list
-			   - Some minor bug fixes

+    Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
     Verified to work with up to 2 DE212 cards in a system (although not
       fully stress-tested).
 
-    Currently known bugs/limitations:
-
-    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
-           not the command line for IRQ and memory address.  You can
-           specify them if you want, but it will throw your values out.
-           You still have to pass the IO address it was configured as
-           though.

-   net-3-driver for the 3c523 Etherlink/MC card (i82586 Ethernet chip)
-
-
-   This is an extension to the Linux operating system, and is covered by the
-   same GNU General Public License that covers that work.
-
-   Copyright 1995, 1996 by Chris Beauregard (cpbeaure@undergrad.math.uwaterloo.ca)
-
-   This is basically Michael Hipp's ni52 driver, with a new probing
-   algorithm and some minor changes to the 82586 CA and reset routines.
-   Thanks a lot Michael for a really clean i82586 implementation!  Unless
-   otherwise documented in ni52.c, any bugs are mine.
-
-   Contrary to the Ethernet-HOWTO, this isn't based on the 3c507 driver in
-   any way.  The ni52 is a lot easier to modify.
-
-   sources:
-   ni52.c
-
-   Crynwr packet driver collection was a great reference for my first
-   attempt at this sucker.  The 3c507 driver also helped, until I noticed
-   that ni52.c was a lot nicer.
-
-   EtherLink/MC: Micro Channel Ethernet Adapter Technical Reference
-   Manual, courtesy of 3Com CardFacts, documents the 3c523-specific
-   stuff.  Information on CardFacts is found in the Ethernet HOWTO.
-   Also see <a href="http://www.3com.com/">
-
-   Microprocessor Communications Support Chips, T.J. Byers, ISBN
-   0-444-01224-9, has a section on the i82586.  It tells you just enough
-   to know that you really don't want to learn how to program the chip.
-
-   The original device probe code was stolen from ps2esdi.c
-
-   Known Problems:
-   Since most of the code was stolen from ni52.c, you'll run across the
-   same bugs in the 0.62 version of ni52.c, plus maybe a few because of
-   the 3c523 idiosynchacies.  The 3c523 has 16K of RAM though, so there
-   shouldn't be the overrun problem that the 8K ni52 has.
-
-   This driver is for a 16K adapter.  It should work fine on the 64K
-   adapters, but it will only use one of the 4 banks of RAM.  Modifying
-   this for the 64K version would require a lot of heinous bank
-   switching, which I'm sure not interested in doing.  If you try to
-   implement a bank switching version, you'll basically have to remember
-   what bank is enabled and do a switch every time you access a memory
-   location that's not current.  You'll also have to remap pointers on
-   the driver side, because it only knows about 16K of the memory.
-   Anyone desperate or masochistic enough to try?
-
-   It seems to be stable now when multiple transmit buffers are used.  I
-   can't see any performance difference, but then I'm working on a 386SX.
-
-   Multicast doesn't work.  It doesn't even pretend to work.  Don't use
-   it.  Don't compile your kernel with multicast support.  I don't know
-   why.
-
-   Features:
-   This driver is useable as a loadable module.  If you try to specify an
-   IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will
-   search the MCA slots until it finds a 3c523 with the specified
-   parameters.
-
-   This driver does support multiple ethernet cards when used as a module
-   (up to MAX_3C523_CARDS, the default being 4)
-
-   This has been tested with both BNC and TP versions, internal and
-   external transceivers.  Haven't tested with the 64K version (that I
-   know of).
-
-   History:
-   Jan 1st, 1996
-   first public release
-   Feb 4th, 1996
-   update to 1.3.59, incorporated multicast diffs from ni52.c
-   Feb 15th, 1996
-   added shared irq support
-   Apr 1999
-   added support for multiple cards when used as a module
-   added option to disable multicast as is causes problems
-       Ganesh Sittampalam <ganesh.sittampalam@magdalen.oxford.ac.uk>
-       Stuart Adamson <stuart.adamson@compsoc.net>
-   Nov 2001
-   added support for ethtool (jgarzik)

-/**
- * DOC: Traps for the unwary
- *
- *	The diagram (Figure 1-1) and the POS summary disagree with the
- *	"Interrupt Level" section in the manual.
- *
- *	The manual contradicts itself when describing the minimum number
- *	buffers in the 'configure lists' command.
- *	My card accepts a buffer config of 4/4.
- *
- *	Setting the SAV BP bit does not save bad packets, but
- *	only enables RX on-card stats collection.
- *
- *	The documentation in places seems to miss things. In actual fact
- *	I've always eventually found everything is documented, it just
- *	requires careful study.
- *
- * DOC: Theory Of Operation
- *
- *	The 3com 3c527 is a 32bit MCA bus mastering adapter with a large
- *	amount of on board intelligence that housekeeps a somewhat dumber
- *	Intel NIC. For performance we want to keep the transmit queue deep
- *	as the card can transmit packets while fetching others from main
- *	memory by bus master DMA. Transmission and reception are driven by
- *	circular buffer queues.
- *
- *	The mailboxes can be used for controlling how the card traverses
- *	its buffer rings, but are used only for initial setup in this
- *	implementation.  The exec mailbox allows a variety of commands to
- *	be executed. Each command must complete before the next is
- *	executed. Primarily we use the exec mailbox for controlling the
- *	multicast lists.  We have to do a certain amount of interesting
- *	hoop jumping as the multicast list changes can occur in interrupt
- *	state when the card has an exec command pending. We defer such
- *	events until the command completion interrupt.
- *
- *	A copy break scheme (taken from 3c59x.c) is employed whereby
- *	received frames exceeding a configurable length are passed
- *	directly to the higher networking layers without incuring a copy,
- *	in what amounts to a time/space trade-off.
- *
- *	The card also keeps a large amount of statistical information
- *	on-board. In a perfect world, these could be used safely at no
- *	cost. However, lacking information to the contrary, processing
- *	them without races would involve so much extra complexity as to
- *	make it unworthwhile to do so. In the end, a hybrid SW/HW
- *	implementation was made necessary --- see mc32_update_stats().
- *
- * DOC: Notes
- *
- *	It should be possible to use two or more cards, but at this stage
- *	only by loading two copies of the same module.
- *
- *	The on-board 82586 NIC has trouble receiving multiple
- *	back-to-back frames and so is likely to drop packets from fast
- *	senders.

+ * The 82599 and the X540 do not have true 64bit nanosecond scale
+ * counter registers. Instead, SYSTIME is defined by a fixed point
+ * system which allows the user to define the scale counter increment
+ * value at every level change of the oscillator driving the SYSTIME
+ * value. For both devices the TIMINCA:IV field defines this
+ * increment. On the X540 device, 31 bits are provided. However on the
+ * 82599 only provides 24 bits. The time unit is determined by the
+ * clock frequency of the oscillator in combination with the TIMINCA
+ * register. When these devices link at 10Gb the oscillator has a
+ * period of 6.4ns. In order to convert the scale counter into
+ * nanoseconds the cyclecounter and timecounter structures are
+ * used. The SYSTIME registers need to be converted to ns values by use
+ * of only a right shift (division by power of 2). The following math
+ * determines the largest incvalue that will fit into the available
+ * bits in the TIMINCA register.
+ *
+ * PeriodWidth: Number of bits to store the clock period
+ * MaxWidth: The maximum width value of the TIMINCA register
+ * Period: The clock period for the oscillator
+ * round(): discard the fractional portion of the calculation
+ *
+ * Period * [ 2 ^ ( MaxWidth - PeriodWidth ) ]
+ *
+ * For the X540, MaxWidth is 31 bits, and the base period is 6.4 ns
+ * For the 82599, MaxWidth is 24 bits, and the base period is 6.4 ns
+ *
+ * The period also changes based on the link speed:
+ * At 10Gb link or no link, the period remains the same.
+ * At 1Gb link, the period is multiplied by 10. (64ns)
+ * At 100Mb link, the period is multiplied by 100. (640ns)
+ *

- * RX ucode for the Intel IXP2400 in POS-PHY mode.
- * Copyright (C) 2004, 2005 Lennert Buytenhek
- * Dedicated to Marija Kulikova.
- *
- * This program is free software; you can redistribute it and/or modify

- * (at your option) any later version.
- *
- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- *   only one full element list is used.  This includes, for example,
- *   1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4.  (This
- *   is not an exhaustive list.)
- * - The RBUF uses 64-byte mpackets.
- * - RX descriptors reside in SRAM, and have the following format:
- *	struct rx_desc
- *	{
- *	// to uengine
- *		u32	buf_phys_addr;
- *		u32	buf_length;
- *
- *	// from uengine
- *		u32	channel;
- *		u32	pkt_length;
- *	};
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 0 is rx_pending.
- * - Scratch ring 1 is rx_done, and has status condition 'full'.
- * - The host triggers rx_done flush and rx_pending refill on seeing INTA.
- * - This code is run on all eight threads of the microengine it runs on.
- *
- * Local memory is used for per-channel RX state.

- * Assumptions made in this code:
- * - The IXP2400 MSF is configured for POS-PHY mode, in a mode where
- *   only one TBUF partition is used.  This includes, for example,
- *   1x32 SPHY and 1x32 MPHY32, but not 4x8 SPHY or 1x32 MPHY4. (This
- *   is not an exhaustive list.)
- * - The TBUF uses 64-byte mpackets.
- * - TX descriptors reside in SRAM, and have the following format:
- *	struct tx_desc
- *	{
- *	// to uengine
- *		u32	buf_phys_addr;
- *		u32	pkt_length;
- *		u32	channel;
- *	};
- * - Packet data resides in DRAM.
- * - Packet buffer addresses are 8-byte aligned.
- * - Scratch ring 2 is tx_pending.
- * - Scratch ring 3 is tx_done, and has status condition 'full'.
- * - This code is run on all eight threads of the microengine it runs on.

- *	Technical Card Details
- *
- *  All access to data is done with 16/8 bit transfers.  The transfer
- *  method really sucks. You can only read or write one location at a time.
- *
- *  Also, the microcode for the card must be uploaded if the card does not have
- *  the flashrom on board.  This is a 28K bloat in the driver when compiled
- *  as a module.
- *
- *  Rx is very simple, status into a ring of descriptors, dma data transfer,
- *  interrupts to tell us when a packet is received.
- *
- *  Tx is a little more interesting. Similar scenario, descriptor and dma data
- *  transfers, but we don't have to interrupt the card to tell it another packet
- *  is ready for transmission, we are just doing simple memory writes, not io or mmio
- *  writes.  The card can be set up to simply poll on the next
- *  descriptor pointer and when this value is non-zero will automatically download
- *  the next packet.  The card then interrupts us when the packet is done.

- *	There are two ways of implementing rx on the 359 NIC, either
- * 	interrupt driven or polling.  We are going to uses interrupts,
- *	it is the easier way of doing things.
- *	
- *	The Rx works with a ring of Rx descriptors.  At initialise time the ring
- *	entries point to the next entry except for the last entry in the ring 
- *	which points to 0.  The card is programmed with the location of the first
- *	available descriptor and keeps reading the next_ptr until next_ptr is set
- *	to 0.  Hopefully with a ring size of 16 the card will never get to read a next_ptr
- *	of 0.  As the Rx interrupt is received we copy the frame up to the protocol layers
- *	and then point the end of the ring to our current position and point our current
- *	position to 0, therefore making the current position the last position on the ring.
- *	The last position on the ring therefore loops continually loops around the rx ring.
- *	
- *	rx_ring_tail is the position on the ring to process next. (Think of a snake, the head 
- *	expands as the card adds new packets and we go around eating the tail processing the
- *	packets.)
- *
- *	Undoubtably it could be streamlined and improved upon, but at the moment it works 
- *	and the fast path through the routine is fine. 
- *	
- *	adv_rx_ring could be inlined to increase performance, but its called a *lot* of times
- *	in xl_rx so would increase the size of the function significantly.

-/* ibmtr.c:  A shared-memory IBM Token Ring 16/4 driver for linux
- *
- *	Written 1993 by Mark Swanson and Peter De Schrijver.
- *	This software may be used and distributed according to the terms
- *	of the GNU General Public License, incorporated herein by reference.
- *
- *	This device driver should work with Any IBM Token Ring Card that does
- *	not use DMA.
- *
- *	I used Donald Becker's (becker@scyld.com) device driver work
- *	as a base for most of my initial work.
- *
- *	Changes by Peter De Schrijver
- *		(Peter.Deschrijver@linux.cc.kuleuven.ac.be) :
- *
- *	+ changed name to ibmtr.c in anticipation of other tr boards.
- *	+ changed reset code and adapter open code.
- *	+ added SAP open code.
- *	+ a first attempt to write interrupt, transmit and receive routines.
- *
- *	Changes by David W. Morris (dwm@shell.portal.com) :
- *	941003 dwm: - Restructure tok_probe for multiple adapters, devices.
- *	+ Add comments, misc reorg for clarity.
- *	+ Flatten interrupt handler levels.
- *
- *	Changes by Farzad Farid (farzy@zen.via.ecp.fr)
- *	and Pascal Andre (andre@chimay.via.ecp.fr) (March 9 1995) :
- *	+ multi ring support clean up.
- *	+ RFC1042 compliance enhanced.
- *
- *	Changes by Pascal Andre (andre@chimay.via.ecp.fr) (September 7 1995) :
- *	+ bug correction in tr_tx
- *	+ removed redundant information display
- *	+ some code reworking
- *
- *	Changes by Michel Lespinasse (walken@via.ecp.fr),
- *	Yann Doussot (doussot@via.ecp.fr) and Pascal Andre (andre@via.ecp.fr)
- *	(February 18, 1996) :
- *	+ modified shared memory and mmio access port the driver to
- *	  alpha platform (structure access -> readb/writeb)
- *
- *	Changes by Steve Kipisz (bungy@ibm.net or kipisz@vnet.ibm.com)
- *	(January 18 1996):
- *	+ swapped WWOR and WWCR in ibmtr.h
- *	+ moved some init code from tok_probe into trdev_init.  The
- *	  PCMCIA code can call trdev_init to complete initializing
- *	  the driver.
- *	+ added -DPCMCIA to support PCMCIA
- *	+ detecting PCMCIA Card Removal in interrupt handler.  If
- *	  ISRP is FF, then a PCMCIA card has been removed
- *        10/2000 Burt needed a new method to avoid crashing the OS
- *
- *	Changes by Paul Norton (pnorton@cts.com) :
- *	+ restructured the READ.LOG logic to prevent the transmit SRB
- *	  from being rudely overwritten before the transmit cycle is
- *	  complete. (August 15 1996)
- *	+ completed multiple adapter support. (November 20 1996)
- *	+ implemented csum_partial_copy in tr_rx and increased receive 
- *        buffer size and count. Minor fixes. (March 15, 1997)
- *
- *	Changes by Christopher Turcksin <wabbit@rtfc.demon.co.uk>
- *	+ Now compiles ok as a module again.
- *
- *	Changes by Paul Norton (pnorton@ieee.org) :
- *      + moved the header manipulation code in tr_tx and tr_rx to
- *        net/802/tr.c. (July 12 1997)
- *      + add retry and timeout on open if cable disconnected. (May 5 1998)
- *      + lifted 2000 byte mtu limit. now depends on shared-RAM size.
- *        May 25 1998)
- *      + can't allocate 2k recv buff at 8k shared-RAM. (20 October 1998)
- *
- *      Changes by Joel Sloan (jjs@c-me.com) :
- *      + disable verbose debug messages by default - to enable verbose
- *	  debugging, edit the IBMTR_DEBUG_MESSAGES define below 
- *	
- *	Changes by Mike Phillips <phillim@amtrak.com> :
- *	+ Added extra #ifdef's to work with new PCMCIA Token Ring Code.
- *	  The PCMCIA code now just sets up the card so it can be recognized
- *        by ibmtr_probe. Also checks allocated memory vs. on-board memory
- *	  for correct figure to use.
- *
- *	Changes by Tim Hockin (thockin@isunix.it.ilstu.edu) :
- *	+ added spinlocks for SMP sanity (10 March 1999)
- *
- *      Changes by Jochen Friedrich to enable RFC1469 Option 2 multicasting
- *      i.e. using functional address C0 00 00 04 00 00 to transmit and 
- *      receive multicast packets.
- *
- *      Changes by Mike Sullivan (based on original sram patch by Dave Grothe
- *      to support windowing into on adapter shared ram.
- *      i.e. Use LANAID to setup a PnP configuration with 16K RAM. Paging
- *      will shift this 16K window over the entire available shared RAM.
- *
- *      Changes by Peter De Schrijver (p2@mind.be) :
- *      + fixed a problem with PCMCIA card removal
- *
- *      Change by Mike Sullivan et al.:
- *      + added turbo card support. No need to use lanaid to configure
- *      the adapter into isa compatibility mode.
- *
- *      Changes by Burt Silverman to allow the computer to behave nicely when
- *	a cable is pulled or not in place, or a PCMCIA card is removed hot.

-/*======================================================================
-
-    A PCMCIA token-ring driver for IBM-based cards
-
-    This driver supports the IBM PCMCIA Token-Ring Card.
-    Written by Steve Kipisz, kipisz@vnet.ibm.com or
-                             bungy@ibm.net
-
-    Written 1995,1996.
-
-    This code is based on pcnet_cs.c from David Hinds.
-    
-    V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
-
-    Linux V2.2.x presented significant changes to the underlying
-    ibmtr.c code.  Mainly the code became a lot more organized and
-    modular.
-
-    This caused the old PCMCIA Token Ring driver to give up and go 
-    home early. Instead of just patching the old code to make it 
-    work, the PCMCIA code has been streamlined, updated and possibly
-    improved.
-
-    This code now only contains code required for the Card Services.
-    All we do here is set the card up enough so that the real ibmtr.c
-    driver can find it and work with it properly.
-
-    i.e. We set up the io port, irq, mmio memory and shared ram
-    memory.  This enables ibmtr_probe in ibmtr.c to find the card and
-    configure it as though it was a normal ISA and/or PnP card.
-
-    CHANGES
-
-    v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
-    Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
-    
-    v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
-    Updated to version 2.2.7 to match the first version of the kernel
-    that the modification to ibmtr.c were incorporated into.
-    
-    v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
-    Address translation feature of PCMCIA controller is usable so
-    memory windows can be placed in High memory (meaning above
-    0xFFFFF.)

- *  12/10/99 - Alpha Release 0.1.0
- *            First release to the public
- *  03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
- *		malloc free checks, reviewed code. <alan@redhat.com>
- *  03/13/00 - Added spinlocks for smp
- *  03/08/01 - Added support for module_init() and module_exit()
- *  08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
- *             calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
- *  11/05/01 - Restructured the interrupt function, added delays, reduced the 
- *             the number of TX descriptors to 1, which together can prevent 
- *             the card from locking up the box - <yoder1@us.ibm.com>
- *  09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
- *  11/13/02 - Removed free_irq calls which could cause a hang, added
- *	       netif_carrier_{on|off} - <yoder1@us.ibm.com>
- *  
- *  To Do:
- *
- *
- *  If Problems do Occur
- *  Most problems can be rectified by either closing and opening the interface
- *  (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- *  if compiled into the kernel).

- * Handle interrupts generated by the card
- *
- * The MicroChannel Madge cards need slightly more handling
- * after an interrupt than other TMS380 cards do.
- *
- * First we must make sure it was this card that generated the
- * interrupt (since interrupt sharing is allowed).  Then,
- * because we're using level-triggered interrupts (as is
- * standard on MCA), we must toggle the interrupt line
- * on the card in order to claim and acknowledge the interrupt.
- * Once that is done, the interrupt should be handlable in
- * the normal tms380tr_interrupt() routine.
- *
- * There's two ways we can check to see if the interrupt is ours,
- * both with their own disadvantages...
- *
- * 1)  	Read in the SIFSTS register from the TMS controller.  This
- *	is guaranteed to be accurate, however, there's a fairly
- *	large performance penalty for doing so: the Madge chips
- *	must request the register from the Eagle, the Eagle must
- *	read them from its internal bus, and then take the route
- *	back out again, for a 16bit read.  
- *
- * 2)	Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
- *	The major disadvantage here is that the accuracy of the
- *	bit is in question.  However, it cuts out the extra read
- *	cycles it takes to read the Eagle's SIF, as its only an
- *	8bit read, and theoretically the Madge bit is directly
- *	connected to the interrupt latch coming out of the Eagle
- *	hardware (that statement is not verified).  
- *
- * I can't determine which of these methods has the best win.  For now,
- * we make a compromise.  Use the Madge way for the first interrupt,
- * which should be the fast-path, and then once we hit the first 
- * interrupt, keep on trying using the SIF method until we've
- * exhausted all contiguous interrupts.

- *
- *  Linux driver for IBM PCI tokenring cards based on the Pit/Pit-Phy/Olympic
- *  chipset. 
- *
- *  Base Driver Skeleton:
- *      Written 1993-94 by Donald Becker.
- *
- *      Copyright 1993 United States Government as represented by the
- *      Director, National Security Agency.
- *
- *  Thanks to Erik De Cock, Adrian Bridgett and Frank Fiene for their 
- *  assistance and perserverance with the testing of this driver.
- *
- *  This software may be used and distributed according to the terms
- *  of the GNU General Public License, incorporated herein by reference.
- * 
- *  4/27/99 - Alpha Release 0.1.0
- *            First release to the public
- *
- *  6/8/99  - Official Release 0.2.0   
- *            Merged into the kernel code 
- *  8/18/99 - Updated driver for 2.3.13 kernel to use new pci
- *	      resource. Driver also reports the card name returned by
- *            the pci resource.
- *  1/11/00 - Added spinlocks for smp
- *  2/23/00 - Updated to dev_kfree_irq 
- *  3/10/00 - Fixed FDX enable which triggered other bugs also 
- *            squashed.
- *  5/20/00 - Changes to handle Olympic on LinuxPPC. Endian changes.
- *            The odd thing about the changes is that the fix for
- *            endian issues with the big-endian data in the arb, asb...
- *            was to always swab() the bytes, no matter what CPU.
- *            That's because the read[wl]() functions always swap the
- *            bytes on the way in on PPC.
- *            Fixing the hardware descriptors was another matter,
- *            because they weren't going through read[wl](), there all
- *            the results had to be in memory in le32 values. kdaaker
- *
- * 12/23/00 - Added minimal Cardbus support (Thanks Donald).
- *
- * 03/09/01 - Add new pci api, dev_base_lock, general clean up. 
- *
- * 03/27/01 - Add new dma pci (Thanks to Kyle Lucke) and alloc_trdev
- *	      Change proc_fs behaviour, now one entry per adapter.
- *
- * 04/09/01 - Couple of bug fixes to the dma unmaps and ejecting the
- *	      adapter when live does not take the system down with it.
- * 
- * 06/02/01 - Clean up, copy skb for small packets
- * 
- * 06/22/01 - Add EISR error handling routines 
- *
- * 07/19/01 - Improve bad LAA reporting, strip out freemem
- *	      into a separate function, its called from 3 
- *	      different places now. 
- * 02/09/02 - Replaced sleep_on. 
- * 03/01/02 - Replace access to several registers from 32 bit to 
- * 	      16 bit. Fixes alignment errors on PPC 64 bit machines.
- * 	      Thanks to Al Trautman for this one.
- * 03/10/02 - Fix BUG in arb_cmd. Bug was there all along but was
- * 	      silently ignored until the error checking code 
- * 	      went into version 1.0.0 
- * 06/04/02 - Add correct start up sequence for the cardbus adapters.
- * 	      Required for strict compliance with pci power mgmt specs.
- *  To Do:
- *
- *	     Wake on lan	
- * 
- *  If Problems do Occur
- *  Most problems can be rectified by either closing and opening the interface
- *  (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
- *  if compiled into the kernel).

- *  tms380tr.c: A network driver library for Texas Instruments TMS380-based
- *              Token Ring Adapters.
- *
- *  Originally sktr.c: Written 1997 by Christoph Goos
- *
- *  A fine result of the Linux Systems Network Architecture Project.
- *  http://www.vanheusden.com/sna/ 
- *
- *  This software may be used and distributed according to the terms
- *  of the GNU General Public License, incorporated herein by reference.
- *
- *  The following modules are currently available for card support:
- *	- tmspci (Generic PCI card support)
- *	- abyss (Madge PCI support)
- *      - tmsisa (SysKonnect TR4/16 ISA)
- *
- *  Sources:
- *  	- The hardware related parts of this driver are take from
- *  	  the SysKonnect Token Ring driver for Windows NT.
- *  	- I used the IBM Token Ring driver 'ibmtr.c' as a base for this
- *  	  driver, as well as the 'skeleton.c' driver by Donald Becker.
- *  	- Also various other drivers in the linux source tree were taken
- *  	  as samples for some tasks.
- *      - TI TMS380 Second-Generation Token Ring User's Guide
- *  	- TI datasheets for respective chips
- *  	- David Hein at Texas Instruments 
- *  	- Various Madge employees

- *  Maintainer(s):
- *    JS	Jay Schulist		jschlst@samba.org
- *    CG	Christoph Goos		cgoos@syskonnect.de
- *    AF	Adam Fritzler
- *    MLP       Mike Phillips           phillim@amtrak.com
- *    JF	Jochen Friedrich	jochen@scram.de
- *     
- *  Modification History:
- *	29-Aug-97	CG	Created
- *	04-Apr-98	CG	Fixed problems caused by tok_timer_check
- *	10-Apr-98	CG	Fixed lockups at cable disconnection
- *	27-May-98	JS	Formated to Linux Kernel Format
- *	31-May-98	JS	Hacked in PCI support
- *	16-Jun-98	JS	Modulized for multiple cards with one driver
- *	   Sep-99	AF	Renamed to tms380tr (supports more than SK's)
- *      23-Sep-99	AF      Added Compaq and Thomas-Conrad PCI support
- *				Fixed a bug causing double copies on PCI
- *				Fixed for new multicast stuff (2.2/2.3)
- *	25-Sep-99	AF	Uped TPL_NUM from 3 to 9
- *				Removed extraneous 'No free TPL'
- *	22-Dec-99	AF	Added Madge PCI Mk2 support and generalized
- *				parts of the initilization procedure.
- *	30-Dec-99	AF	Turned tms380tr into a library ala 8390.
- *				Madge support is provided in the abyss module
- *				Generic PCI support is in the tmspci module.
- *	30-Nov-00	JF	Updated PCI code to support IO MMU via
- *				pci_map_static(). Alpha uses this MMU for ISA
- *				as well.
- *      14-Jan-01	JF	Fix DMA on ifdown/ifup sequences. Some 
- *      			cleanup.
- *	13-Jan-02	JF	Add spinlock to fix race condition.
- *	09-Nov-02	JF	Fixed printks to not SPAM the console during
- *				normal operation.
- *	30-Dec-02	JF	Removed incorrect __init from 
- *				tms380tr_init_card.
- *	22-Jul-05	JF	Converted to dma-mapping.
- *      			
- *  To do:
- *    1. Multi/Broadcast packet handling (this may have fixed itself)
- *    2. Write a sktrisa module that includes the old ISA support (done)
- *    3. Allow modules to load their own microcode
- *    4. Speed up the BUD process -- freezing the kernel for 3+sec is
- *         quite unacceptable.
- *    5. Still a few remaining stalls when the cable is unplugged.

- * DOC: shared area - role and goal
- *
- * The shared area contains all the data exported by the upper layer to the
- * other layers. Since the bus and transport layer shouldn't dereference
- * iwl_priv, all the data needed by the upper layer and the transport / bus
- * layer must be here.
- * The shared area also holds pointer to all the other layers. This allows a
- * layer to call a function from another layer.
- *
- * NOTE: All the layers hold a pointer to the shared area which must be shrd.
- *	A few macros assume that (_m)->shrd points to the shared area no matter
- *	what _m is.
- *
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c

-
-	  Note: display switching code is currently considered EXPERIMENTAL,

+	  The Configurable Composite Gadget supports multiple USB
+	  functions: acm, mass storage, rndis and FunctionFS.
+	  Each function can be configured and enabled/disabled
+	  dynamically from userspace through a sysfs interface.
+
+	  In order to compile this (either as a module or built-in),
+	  "USB Gadget Drivers" and anything under it must not be
+	  selected compiled-in in
+	  Device Drivers->USB Support->USB Gadget Support.
+	  However, you can say "M" there, if you do, the
+	  Configurable Composite Gadget can be compiled "M" only
+	  or not at all.

-Description:
-		Description of the scan element data storage within the buffer
-		and hence the form in which it is read from user-space.
-		Form is [be|le]:[s|u]bits/storagebits[>>shift].
-		be or le specifies big or little endian. s or u specifies if
-		signed (2's complement) or unsigned. bits is the number of bits
-		of data and storagebits is the space (after padding) that it
-		occupies in the buffer. shift if specified, is the shift that
-		needs to be applied prior to masking out unused bits. Some
-		devices put their data in the middle of the transferred elements
-		with additional information on both sides.  Note that some
-		devices will have additional information in the unused bits
-		so to get a clean value, the bits value must be used to mask
-		the buffer output value appropriately.  The storagebits value
-		also specifies the data alignment.  So s48/64>>2 will be a
-		signed 48 bit integer stored in a 64 bit location aligned to
-		a a64 bit boundary. To obtain the clean value, shift right 2
-		and apply a mask to zero the top 16 bits of the result.
-		For other storage combinations this attribute will be extended
-		appropriately.

+				TODO
+				====
+Introduction
+============
+
+These drivers add support for IndustryPack devices: carrier and mezzanine
+boards.
+
+The ipack driver is just an abstraction of the bus providing the common
+operations between the two kind of boards.
+
+TODO
+====
+
+TPCI-200
+--------
+
+* It receives the name of the mezzanine plugged in each slot by SYSFS.
+  No autodetection supported yet, because the mezzanine driver could not be
+  loaded at the time that the tpci200 driver loads.
+
+* It has a linked list with the tpci200 devices it is managing. Get rid of it
+  and use driver_for_each_device() instead.
+
+IP-OCTAL
+--------
+
+* It has a linked list which saves the devices it is currently
+  managing. It should use the driver_for_each_device() function. It is not there
+  due to the impossibility of using container_of macro to recover the
+  corresponding "struct ipoctal" because the attribute "struct ipack_device" is
+  a pointer. This code should be refactored.
+
+Ipack
+-----
+
+* The structures and API exported can be improved a lot. For example, the
+  way to unregistering mezzanine devices, doing the mezzanine driver a call to
+  remove_device() to notify the carrier driver, or the opposite with the call to
+  the ipack_driver_ops' remove() function could be improved.

-Intel(R) Management Engine Interface (Intel(R) MEI)
-=======================
-
-Introduction
-=======================
-
-The Intel Management Engine (Intel ME) is an isolated and protected computing
-resource (Co-processor) residing inside certain Intel chipsets. The Intel ME
-provides support for computer/IT management features. The feature set
-depends on the Intel chipset SKU.
-
-The Intel Management Engine Interface (Intel MEI, previously known as HECI)
-is the interface between the Host and Intel ME. This interface is exposed
-to the host as a PCI device. The Intel MEI Driver is in charge of the
-communication channel between a host application and the Intel ME feature.
-
-Each Intel ME feature (Intel ME Client) is addressed by a GUID/UUID and
-each client has its own protocol. The protocol is message-based with a
-header and payload up to 512 bytes.
-
-Prominent usage of the Intel ME Interface is to communicate with Intel(R)
-Active Management Technology (Intel AMT)implemented in firmware running on
-the Intel ME.
-
-Intel AMT provides the ability to manage a host remotely out-of-band (OOB)
-even when the operating system running on the host processor has crashed or
-is in a sleep state.
-
-Some examples of Intel AMT usage are:
-   - Monitoring hardware state and platform components
-   - Remote power off/on (useful for green computing or overnight IT
-     maintenance)
-   - OS updates
-   - Storage of useful platform information such as software assets
-   - Built-in hardware KVM
-   - Selective network isolation of Ethernet and IP protocol flows based
-     on policies set by a remote management console
-   - IDE device redirection from remote management console
-
-Intel AMT (OOB) communication is based on SOAP (deprecated
-starting with Release 6.0) over HTTP/S or WS-Management protocol over
-HTTP/S that are received from a remote management console application.
-
-For more information about Intel AMT:
-http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-
-Intel MEI Driver
-=======================
-
-The driver exposes a misc device called /dev/mei.
-
-An application maintains communication with an Intel ME feature while
-/dev/mei is open. The binding to a specific features is performed by calling
-MEI_CONNECT_CLIENT_IOCTL, which passes the desired UUID.
-The number of instances of an Intel ME feature that can be opened
-at the same time depends on the Intel ME feature, but most of the
-features allow only a single instance.
-
-The Intel AMT Host Interface (Intel AMTHI) feature supports multiple
-simultaneous user applications. Therefore, the Intel MEI driver handles
-this internally by maintaining request queues for the applications.
-
-The driver is oblivious to data that is passed between firmware feature
-and host application.
-
-Because some of the Intel ME features can change the system
-configuration, the driver by default allows only a privileged
-user to access it.
-
-A code snippet for an application communicating with
-Intel AMTHI client:
-	struct mei_connect_client_data data;
-	fd = open(MEI_DEVICE);
-
-	data.d.in_client_uuid = AMTHI_UUID;
-
-	ioctl(fd, IOCTL_MEI_CONNECT_CLIENT, &data);
-
-	printf("Ver=%d, MaxLen=%ld\n",
-			data.d.in_client_uuid.protocol_version,
-			data.d.in_client_uuid.max_msg_length);
-
-	[...]
-
-	write(fd, amthi_req_data, amthi_req_data_len);
-
-	[...]
-
-	read(fd, &amthi_res_data, amthi_res_data_len);
-
-	[...]
-	close(fd);
-
-IOCTL:
-======
-The Intel MEI Driver supports the following IOCTL command:
-	IOCTL_MEI_CONNECT_CLIENT	Connect to firmware Feature (client).
-
-	usage:
-		struct mei_connect_client_data clientData;
-		ioctl(fd, IOCTL_MEI_CONNECT_CLIENT, &clientData);
-
-	inputs:
-		mei_connect_client_data struct contain the following
-		input field:
-
-		in_client_uuid -	UUID of the FW Feature that needs
-					to connect to.
-	outputs:
-		out_client_properties - Client Properties: MTU and Protocol Version.
-
-	error returns:
-		EINVAL	Wrong IOCTL Number
-		ENODEV	Device or Connection is not initialized or ready.
-			(e.g. Wrong UUID)
-		ENOMEM	Unable to allocate memory to client internal data.
-		EFAULT	Fatal Error (e.g. Unable to access user input data)
-		EBUSY	Connection Already Open
-
-	Notes:
-        max_msg_length (MTU) in client properties describes the maximum
-        data that can be sent or received. (e.g. if MTU=2K, can send
-        requests up to bytes 2k and received responses upto 2k bytes).
-
-Intel ME Applications:
-==============
-
-1) Intel Local Management Service (Intel LMS)
-
-	Applications running locally on the platform communicate with Intel AMT Release
-	2.0 and later releases in the same way that network applications do via SOAP
-	over HTTP (deprecated starting with Release 6.0) or with WS-Management over
-	SOAP over HTTP. This means that some Intel AMT features can be accessed from a
-	local application using the same network interface as a remote application
-	communicating with Intel AMT over the network.
-
-	When a local application sends a message addressed to the local Intel AMT host
-	name, the Intel LMS, which listens for traffic directed to the host name,
-	intercepts the message and routes it to the Intel MEI.
-	For more information:
-	http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-	Under "About Intel AMT" => "Local Access"
-
-	For downloading Intel LMS:
-	http://software.intel.com/en-us/articles/download-the-latest-intel-amt-open-source-drivers/
-
-	The Intel LMS opens a connection using the Intel MEI driver to the Intel LMS
-	firmware feature using a defined UUID and then communicates with the feature
-	using a protocol called Intel AMT Port Forwarding Protocol(Intel APF protocol).
-	The protocol is used to maintain multiple sessions with Intel AMT from a
-	single application.
-
-	See the protocol specification in the Intel AMT Software Development Kit(SDK)
-	http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-	Under "SDK Resources" => "Intel(R) vPro(TM) Gateway(MPS)"
-	=> "Information for Intel(R) vPro(TM) Gateway Developers"
-	=> "Description of the Intel AMT Port Forwarding (APF)Protocol"
-
-  2) Intel AMT Remote configuration using a Local Agent
-	A Local Agent enables IT personnel to configure Intel AMT out-of-the-box
-	without requiring installing additional data to enable setup. The remote
-	configuration process may involve an ISV-developed remote configuration
-	agent that runs on the host.
-	For more information:
-	http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide
-	Under "Setup and Configuration of Intel AMT" =>
-	"SDK Tools Supporting Setup and Configuration" =>
-	"Using the Local Agent Sample"
-
-	An open source Intel AMT configuration utility,	implementing a local agent
-	that accesses the Intel MEI driver, can be found here:
-	http://software.intel.com/en-us/articles/download-the-latest-intel-amt-open-source-drivers/
-
-
-Intel AMT OS Health Watchdog:
-=============================
-The Intel AMT Watchdog is an OS Health (Hang/Crash) watchdog.
-Whenever the OS hangs or crashes, Intel AMT will send an event
-to any subscriber to this event. This mechanism means that
-IT knows when a platform crashes even when there is a hard failure on the host.
-
-The Intel AMT Watchdog is composed of two parts:
-	1) Firmware feature - receives the heartbeats
-	   and sends an event when the heartbeats stop.
-	2) Intel MEI driver - connects to the watchdog feature, configures the
-	   watchdog and sends the heartbeats.
-
-The Intel MEI driver uses the kernel watchdog to configure the Intel AMT
-Watchdog and to send heartbeats to it. The default timeout of the
-watchdog is 120 seconds.
-
-If the Intel AMT Watchdog feature does not exist (i.e. the connection failed),
-the Intel MEI driver will disable the sending of heartbeats.
-

-	  Some hardware has an incorrect product string and announces itself as
-	  ESU-100 (which uses the serqt driver) even though it is an ESU2-100.
-	  Check the label on the bottom of your device.
-
-	  To compile this driver as a module, choose M here: the module will be
-	  called quatech_usb2 .

- *    gathered all the good ideas from all asm-foo/byteorder.h into one file,
- *    cleaned them up.
- *    I hope it is compliant with non-GCC compilers.
- *    I decided to put __BYTEORDER_HAS_U64__ in byteorder.h,

- *    Upgraded it to 2.1.43
- * Francois-Rene Rideau <fare@tunes.org> 19971012
- *    Upgraded it to 2.1.57
- *    to please Linus T., replaced huge #ifdef's between little/big endian
- *    by nestedly #include'd files.
- * Francois-Rene Rideau <fare@tunes.org> 19971205
- *    Made it to 2.1.71; now a facelift:
- *    Put files under include/linux/byteorder/
- *    Split swab from generic support.
- *
- * TODO:
- *   = Regular kernel maintainers could also replace all these manual
- *    byteswap macros that remain, disseminated among drivers,
- *    after some grep or the sources...
- *   = Linus might want to rename all these macros and files to fit his taste,
- *    to fit his personal naming scheme.
- *   = it seems that a few drivers would also appreciate
- *    nybble swapping support...
- *   = every architecture could add their byteswap macro in asm/byteorder.h
- *    see how some architectures already do (i386, alpha, ppc, etc)
- *   = cpu_to_beXX and beXX_to_cpu might some day need to be well
- *    distinguished throughout the kernel. This is not the case currently,
- *    since little endian, big endian, and pdp endian machines needn't it.
- *    But this might be the case for, say, a port of Linux to 20/21 bit

-			VME Device Driver API
-			=====================
-
-Driver registration
-===================
-
-As with other subsystems within the Linux kernel, VME device drivers register
-with the VME subsystem, typically called from the devices init routine.  This is
-achieved via a call to the following function:
-
-	int vme_register_driver (struct vme_driver *driver);
-
-If driver registration is successful this function returns zero, if an error
-occurred a negative error code will be returned.
-
-A pointer to a structure of type 'vme_driver' must be provided to the
-registration function. The structure is as follows:
-
-	struct vme_driver {
-		struct list_head node;
-		const char *name;
-		int (*match)(struct vme_dev *);
-		int (*probe)(struct vme_dev *);
-		int (*remove)(struct vme_dev *);
-		void (*shutdown)(void);
-		struct device_driver driver;
-		struct list_head devices;
-		unsigned int ndev;
-	};
-
-At the minimum, the '.name', '.match' and '.probe' elements of this structure
-should be correctly set. The '.name' element is a pointer to a string holding
-the device driver's name.
-
-The '.match' function allows controlling the number of devices that need to
-be registered. The match function should return 1 if a device should be
-probed and 0 otherwise. This example match function (from vme_user.c) limits
-the number of devices probed to one:
-
-	#define USER_BUS_MAX	1
-	...
-	static int vme_user_match(struct vme_dev *vdev)
-	{
-		if (vdev->id.num >= USER_BUS_MAX)
-			return 0;
-		return 1;
-	}
-
-The '.probe' element should contain a pointer to the probe routine. The
-probe routine is passed a 'struct vme_dev' pointer as an argument. The
-'struct vme_dev' structure looks like the following:
-
-	struct vme_dev {
-		int num;
-		struct vme_bridge *bridge;
-		struct device dev;
-		struct list_head drv_list;
-		struct list_head bridge_list;
-	};
-
-Here, the 'num' field refers to the sequential device ID for this specific
-driver. The bridge number (or bus number) can be accessed using
-dev->bridge->num.
-
-A function is also provided to unregister the driver from the VME core and is
-usually called from the device driver's exit routine:
-
-	void vme_unregister_driver (struct vme_driver *driver);
-
-
-Resource management
-===================
-
-Once a driver has registered with the VME core the provided match routine will
-be called the number of times specified during the registration. If a match
-succeeds, a non-zero value should be returned. A zero return value indicates
-failure. For all successful matches, the probe routine of the corresponding
-driver is called. The probe routine is passed a pointer to the devices
-device structure. This pointer should be saved, it will be required for
-requesting VME resources.
-
-The driver can request ownership of one or more master windows, slave windows
-and/or dma channels. Rather than allowing the device driver to request a
-specific window or DMA channel (which may be used by a different driver) this
-driver allows a resource to be assigned based on the required attributes of the
-driver in question:
-
-	struct vme_resource * vme_master_request(struct vme_dev *dev,
-		u32 aspace, u32 cycle, u32 width);
-
-	struct vme_resource * vme_slave_request(struct vme_dev *dev, u32 aspace,
-		u32 cycle);
-
-	struct vme_resource *vme_dma_request(struct vme_dev *dev, u32 route);
-
-For slave windows these attributes are split into the VME address spaces that
-need to be accessed in 'aspace' and VME bus cycle types required in 'cycle'.
-Master windows add a further set of attributes in 'width' specifying the
-required data transfer widths. These attributes are defined as bitmasks and as
-such any combination of the attributes can be requested for a single window,
-the core will assign a window that meets the requirements, returning a pointer
-of type vme_resource that should be used to identify the allocated resource
-when it is used. For DMA controllers, the request function requires the
-potential direction of any transfers to be provided in the route attributes.
-This is typically VME-to-MEM and/or MEM-to-VME, though some hardware can
-support VME-to-VME and MEM-to-MEM transfers as well as test pattern generation.
-If an unallocated window fitting the requirements can not be found a NULL
-pointer will be returned.
-
-Functions are also provided to free window allocations once they are no longer
-required. These functions should be passed the pointer to the resource provided
-during resource allocation:
-
-	void vme_master_free(struct vme_resource *res);
-
-	void vme_slave_free(struct vme_resource *res);
-
-	void vme_dma_free(struct vme_resource *res);
-
-
-Master windows
-==============
-
-Master windows provide access from the local processor[s] out onto the VME bus.
-The number of windows available and the available access modes is dependent on
-the underlying chipset. A window must be configured before it can be used.
-
-
-Master window configuration
----------------------------
-
-Once a master window has been assigned the following functions can be used to
-configure it and retrieve the current settings:
-
-	int vme_master_set (struct vme_resource *res, int enabled,
-		unsigned long long base, unsigned long long size, u32 aspace,
-		u32 cycle, u32 width);
-
-	int vme_master_get (struct vme_resource *res, int *enabled,
-		unsigned long long *base, unsigned long long *size, u32 *aspace,
-		u32 *cycle, u32 *width);
-
-The address spaces, transfer widths and cycle types are the same as described
-under resource management, however some of the options are mutually exclusive.
-For example, only one address space may be specified.
-
-These functions return 0 on success or an error code should the call fail.
-
-
-Master window access
---------------------
-
-The following functions can be used to read from and write to configured master
-windows. These functions return the number of bytes copied:
-
-	ssize_t vme_master_read(struct vme_resource *res, void *buf,
-		size_t count, loff_t offset);
-
-	ssize_t vme_master_write(struct vme_resource *res, void *buf,
-		size_t count, loff_t offset);
-
-In addition to simple reads and writes, a function is provided to do a
-read-modify-write transaction. This function returns the original value of the
-VME bus location :
-
-	unsigned int vme_master_rmw (struct vme_resource *res,
-		unsigned int mask, unsigned int compare, unsigned int swap,
-		loff_t offset);
-
-This functions by reading the offset, applying the mask. If the bits selected in
-the mask match with the values of the corresponding bits in the compare field,
-the value of swap is written the specified offset.
-
-
-Slave windows
-=============
-
-Slave windows provide devices on the VME bus access into mapped portions of the
-local memory. The number of windows available and the access modes that can be
-used is dependent on the underlying chipset. A window must be configured before
-it can be used.
-
-
-Slave window configuration
---------------------------
-
-Once a slave window has been assigned the following functions can be used to
-configure it and retrieve the current settings:
-
-	int vme_slave_set (struct vme_resource *res, int enabled,
-		unsigned long long base, unsigned long long size,
-		dma_addr_t mem, u32 aspace, u32 cycle);
-
-	int vme_slave_get (struct vme_resource *res, int *enabled,
-		unsigned long long *base, unsigned long long *size,
-		dma_addr_t *mem, u32 *aspace, u32 *cycle);
-
-The address spaces, transfer widths and cycle types are the same as described
-under resource management, however some of the options are mutually exclusive.
-For example, only one address space may be specified.
-
-These functions return 0 on success or an error code should the call fail.
-
-
-Slave window buffer allocation
-------------------------------
-
-Functions are provided to allow the user to allocate and free a contiguous
-buffers which will be accessible by the VME bridge. These functions do not have
-to be used, other methods can be used to allocate a buffer, though care must be
-taken to ensure that they are contiguous and accessible by the VME bridge:
-
-	void * vme_alloc_consistent(struct vme_resource *res, size_t size,
-		dma_addr_t *mem);
-
-	void vme_free_consistent(struct vme_resource *res, size_t size,
-		void *virt,	dma_addr_t mem);
-
-
-Slave window access
--------------------
-
-Slave windows map local memory onto the VME bus, the standard methods for
-accessing memory should be used.
-
-
-DMA channels
-============
-
-The VME DMA transfer provides the ability to run link-list DMA transfers. The
-API introduces the concept of DMA lists. Each DMA list is a link-list which can
-be passed to a DMA controller. Multiple lists can be created, extended,
-executed, reused and destroyed.
-
-
-List Management
----------------
-
-The following functions are provided to create and destroy DMA lists. Execution
-of a list will not automatically destroy the list, thus enabling a list to be
-reused for repetitive tasks:
-
-	struct vme_dma_list *vme_new_dma_list(struct vme_resource *res);
-
-	int vme_dma_list_free(struct vme_dma_list *list);
-
-
-List Population
----------------
-
-An item can be added to a list using the following function ( the source and
-destination attributes need to be created before calling this function, this is
-covered under "Transfer Attributes"):
-
-	int vme_dma_list_add(struct vme_dma_list *list,
-		struct vme_dma_attr *src, struct vme_dma_attr *dest,
-		size_t count);
-
-NOTE:	The detailed attributes of the transfers source and destination
-	are not checked until an entry is added to a DMA list, the request
-	for a DMA channel purely checks the directions in which the
-	controller is expected to transfer data. As a result it is
-	possible for this call to return an error, for example if the
-	source or destination is in an unsupported VME address space.
-
-Transfer Attributes
--------------------
-
-The attributes for the source and destination are handled separately from adding
-an item to a list. This is due to the diverse attributes required for each type
-of source and destination. There are functions to create attributes for PCI, VME
-and pattern sources and destinations (where appropriate):
-
-Pattern source:
-
-	struct vme_dma_attr *vme_dma_pattern_attribute(u32 pattern, u32 type);
-
-PCI source or destination:
-
-	struct vme_dma_attr *vme_dma_pci_attribute(dma_addr_t mem);
-
-VME source or destination:
-
-	struct vme_dma_attr *vme_dma_vme_attribute(unsigned long long base,
-		u32 aspace, u32 cycle, u32 width);
-
-The following function should be used to free an attribute:
-
-	void vme_dma_free_attribute(struct vme_dma_attr *attr);
-
-
-List Execution
---------------
-
-The following function queues a list for execution. The function will return
-once the list has been executed:
-
-	int vme_dma_list_exec(struct vme_dma_list *list);
-
-
-Interrupts
-==========
-
-The VME API provides functions to attach and detach callbacks to specific VME
-level and status ID combinations and for the generation of VME interrupts with
-specific VME level and status IDs.
-
-
-Attaching Interrupt Handlers
-----------------------------
-
-The following functions can be used to attach and free a specific VME level and
-status ID combination. Any given combination can only be assigned a single
-callback function. A void pointer parameter is provided, the value of which is
-passed to the callback function, the use of this pointer is user undefined:
-
-	int vme_irq_request(struct vme_dev *dev, int level, int statid,
-		void (*callback)(int, int, void *), void *priv);
-
-	void vme_irq_free(struct vme_dev *dev, int level, int statid);
-
-The callback parameters are as follows. Care must be taken in writing a callback
-function, callback functions run in interrupt context:
-
-	void callback(int level, int statid, void *priv);
-
-
-Interrupt Generation
---------------------
-
-The following function can be used to generate a VME interrupt at a given VME
-level and VME status ID:
-
-	int vme_irq_generate(struct vme_dev *dev, int level, int statid);
-
-
-Location monitors
-=================
-
-The VME API provides the following functionality to configure the location
-monitor.
-
-
-Location Monitor Management
----------------------------
-
-The following functions are provided to request the use of a block of location
-monitors and to free them after they are no longer required:
-
-	struct vme_resource * vme_lm_request(struct vme_dev *dev);
-
-	void vme_lm_free(struct vme_resource * res);
-
-Each block may provide a number of location monitors, monitoring adjacent
-locations. The following function can be used to determine how many locations
-are provided:
-
-	int vme_lm_count(struct vme_resource * res);
-
-
-Location Monitor Configuration
-------------------------------
-
-Once a bank of location monitors has been allocated, the following functions
-are provided to configure the location and mode of the location monitor:
-
-	int vme_lm_set(struct vme_resource *res, unsigned long long base,
-		u32 aspace, u32 cycle);
-
-	int vme_lm_get(struct vme_resource *res, unsigned long long *base,
-		u32 *aspace, u32 *cycle);
-
-
-Location Monitor Use
---------------------
-
-The following functions allow a callback to be attached and detached from each
-location monitor location. Each location monitor can monitor a number of
-adjacent locations:
-
-	int vme_lm_attach(struct vme_resource *res, int num,
-		void (*callback)(int));
-
-	int vme_lm_detach(struct vme_resource *res, int num);
-
-The callback function is declared as follows.
-
-	void callback(int num);
-
-
-Slot Detection
-==============
-
-This function returns the slot ID of the provided bridge.
-
-	int vme_slot_get(struct vme_dev *dev);

+ * Description: ChipIdea USB IP core family device controller
+ *
+ * This driver is composed of several blocks:
+ * - HW:     hardware interface
+ * - DBG:    debug facilities (optional)
+ * - UTIL:   utilities
+ * - ISR:    interrupts handling
+ * - ENDPT:  endpoint operations (Gadget API)
+ * - GADGET: gadget operations (Gadget API)
+ * - BUS:    bus glue code, bus abstraction layer
+ *
+ * Compile Options
+ * - CONFIG_USB_GADGET_DEBUG_FILES: enable debug facilities
+ * - STALL_IN:  non-empty bulk-in pipes cannot be halted
+ *              if defined mass storage compliance succeeds but with warnings
+ *              => case 4: Hi >  Dn
+ *              => case 5: Hi >  Di
+ *              => case 8: Hi <> Do
+ *              if undefined usbtest 13 fails
+ * - TRACE:     enable function tracing (depends on DEBUG)
+ *
+ * Main Features
+ * - Chapter 9 & Mass Storage Compliance with Gadget File Storage
+ * - Chapter 9 Compliance with Gadget Zero (STALL_IN undefined)
+ * - Normal & LPM support
+ *
+ * USBTEST Report
+ * - OK: 0-12, 13 (STALL_IN defined) & 14
+ * - Not Supported: 15 & 16 (ISO)
+ *
+ * TODO List
+ * - OTG
+ * - Isochronous & Interrupt Traffic
+ * - Handle requests which spawns into several TDs
+ * - GET_STATUS(device) - always reports 0
+ * - Gadget API (majority of optional features)
+ * - Suspend & Remote Wakeup

-	  which lists the devices currently connected to your USB bus or
-	  busses, and for every connected device a file named
-	  "/proc/bus/usb/xxx/yyy", where xxx is the bus number and yyy the
-	  device number; the latter files can be used by user space programs
-	  to talk directly to the device. These files are "virtual", meaning
-	  they are generated on the fly and not stored on the hard drive.
-
-	  You may need to mount the usbfs file system to see the files, use
-	  mount -t usbfs none /proc/bus/usb
-
-	  For the format of the various /proc/bus/usb/ files, please read
-	  <file:Documentation/usb/proc_usb_info.txt>.
-
-	  Modern Linux systems do not use this.
-
-	  Usbfs entries are files and not character devices; usbfs can't
-	  handle Access Control Lists (ACL) which are the default way to
-	  grant access to USB devices for untrusted users of a desktop

-	  Userspace access to USB devices is granted by device-nodes exported

-	  core and udev needed additional class devices to export device nodes.
-
-	  These additional devices are difficult to handle in userspace, if
-	  information about USB interfaces must be available. One device
-	  contains the device node, the other device contains the interface
-	  data. Both devices are at the same level in sysfs (siblings) and one
-	  can't access the other. The device node created directly by the
-	  usb device is the parent device of the interface and therefore
-	  easily accessible from the interface event.

-	  This option provides backward compatibility for libusb device

- * Description: MIPS USB IP core family device controller
- *              Currently it only supports IP part number CI13412
- *
- * This driver is composed of several blocks:
- * - HW:     hardware interface
- * - DBG:    debug facilities (optional)
- * - UTIL:   utilities
- * - ISR:    interrupts handling
- * - ENDPT:  endpoint operations (Gadget API)
- * - GADGET: gadget operations (Gadget API)
- * - BUS:    bus glue code, bus abstraction layer
- *
- * Compile Options
- * - CONFIG_USB_GADGET_DEBUG_FILES: enable debug facilities
- * - STALL_IN:  non-empty bulk-in pipes cannot be halted
- *              if defined mass storage compliance succeeds but with warnings
- *              => case 4: Hi >  Dn
- *              => case 5: Hi >  Di
- *              => case 8: Hi <> Do
- *              if undefined usbtest 13 fails
- * - TRACE:     enable function tracing (depends on DEBUG)
- *
- * Main Features
- * - Chapter 9 & Mass Storage Compliance with Gadget File Storage
- * - Chapter 9 Compliance with Gadget Zero (STALL_IN undefined)
- * - Normal & LPM support
- *
- * USBTEST Report
- * - OK: 0-12, 13 (STALL_IN defined) & 14
- * - Not Supported: 15 & 16 (ISO)
- *
- * TODO List
- * - OTG
- * - Isochronous & Interrupt Traffic
- * - Handle requests which spawns into several TDs
- * - GET_STATUS(device) - always reports 0
- * - Gadget API (majority of optional features)
- * - Suspend & Remote Wakeup
