+By the same token, RCU can be thought of as a "bulk reference count",
+where some form of reference counter covers all reference by a given CPU
+or thread during a set timeframe. This timeframe is related to, but
+not necessarily exactly the same as, an RCU grace period. In classic
+RCU, the reference counter is the per-CPU bit in the "bitmask" field,
+and each such bit covers all references that might have been made by
+the corresponding CPU during the prior grace period. Of course, RCU

+ * device signature). This is worked around by merging the SCR values
+ * into one sensible value and requesting follow-up SRST after
+ * hardreset.
+ *
+ * SCR merging is perfomed in nibbles which is the unit contents in
+ * SCRs are organized. If two values are equal, the value is used.
+ * When they differ, merge table which lists precedence of possible
+ * values is consulted and the first match or the last entry when
+ * nothing matches is used. When there's no merge table for the
+ * specific nibble, value from the first port is used.

+ Basic firmware description. This will remain with
+ the driver for documentation purposes.
+
+ This represents an I2C firmware file encoded as a
+ string of unsigned char. Format is as follows:
+
+ char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB
+ char[1 ]=len0_LSB -> length of first write transaction
+ char[2 ]=data0 -> first byte to be sent
+ char[3 ]=data1
+ char[4 ]=data2
+ char[ ]=...
+ char[M ]=dataN -> last byte to be sent
+ char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB
+ char[M+2]=len1_LSB -> length of second write transaction
+ char[M+3]=data0
+ char[M+4]=data1
+ ...
+ etc.
+
+ The [len] value should be interpreted as follows:
+
+ len= len_MSB _ len_LSB
+ len=1111_1111_1111_1111 : End of I2C_SEQUENCE
+ len=0000_0000_0000_0000 : Reset command: Do hardware reset
+ len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767)
+ len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms
+
+ For the RESET and WAIT commands, the two following bytes will contain
+ immediately the length of the following transaction.

+ * History:

+ * Version 1.0.0
+ * - First working version
+ * 2008-01-13 Tobias Lorenz <tobias.lorenz@gmx.net>
+ * Version 1.0.1
+ * - Improved error handling, every function now returns errno
+ * - Improved multi user access (start/mute/stop)
+ * - Channel doesn't get lost anymore after start/mute/stop
+ * - RDS support added (polling mode via interrupt EP 1)
+ * - marked default module parameters with *value*
+ * - switched from bit structs to bit masks
+ * - header file cleaned and integrated
+ * 2008-01-14 Tobias Lorenz <tobias.lorenz@gmx.net>
+ * Version 1.0.2
+ * - hex values are now lower case
+ * - commented USB ID for ADS/Tech moved on todo list
+ * - blacklisted si470x in hid-quirks.c
+ * - rds buffer handling functions integrated into *_work, *_read
+ * - rds_command in si470x_poll exchanged against simple retval
+ * - check for firmware version 15
+ * - code order and prototypes still remain the same
+ * - spacing and bottom of band codes remain the same
+ * 2008-01-16 Tobias Lorenz <tobias.lorenz@gmx.net>
+ * Version 1.0.3
+ * - code reordered to avoid function prototypes
+ * - switch/case defaults are now more user-friendly
+ * - unified comment style
+ * - applied all checkpatch.pl v1.12 suggestions
+ * except the warning about the too long lines with bit comments
+ * - renamed FMRADIO to RADIO to cut line length (checkpatch.pl)
+ * 2008-01-22 Tobias Lorenz <tobias.lorenz@gmx.net>
+ * Version 1.0.4
+ * - avoid poss. locking when doing copy_to_user which may sleep
+ * - RDS is automatically activated on read now
+ * - code cleaned of unnecessary rds_commands
+ * - USB Vendor/Product ID for ADS/Tech FM Radio Receiver verified
+ * (thanks to Guillaume RAMOUSSE)
+ *
+ * ToDo:
+ * - add seeking support
+ * - add firmware download/update support
+ * - RDS support: interrupt mode, instead of polling
+ * - add LED status output (check if that's not already done in firmware)

-
- This single function is key to pretty much everything. The pvrusb2
- device can logically be viewed as a series of subsystems which can be
- stopped / started or unconfigured / configured. To get things streaming,
- one must configure everything and start everything, but there may be
- various reasons over time to deconfigure something or stop something.
- This function handles all of this activity. Everything EVERYWHERE that
- must affect a subsystem eventually comes here to do the work.
-
- The current state of all subsystems is represented by a single bit mask,
- known as subsys_enabled_mask. The bit positions are defined by the
- PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any
- time the set of configured or active subsystems can be queried just by
- looking at that mask. To change bits in that mask, this function here
- must be called. The "msk" argument indicates which bit positions to
- change, and the "val" argument defines the new values for the positions
- defined by "msk".
-
- There is a priority ordering of starting / stopping things, and for
- multiple requested changes, this function implements that ordering.
- (Thus we will act on a request to load encoder firmware before we
- configure the encoder.) In addition to priority ordering, there is a
- recovery strategy implemented here. If a particular step fails and we
- detect that failure, this function will clear the affected subsystem bits
- and restart. Thus we have a means for recovering from a dead encoder:
- Clear all bits that correspond to subsystems that we need to restart /
- reconfigure and start over.
