 with example pseudo-code.  For a concise description of the API, see
 DMA-API.txt.
 
-Most of the 64bit platforms have special hardware that translates bus
-addresses (DMA addresses) into physical addresses.  This is similar to
-how page tables and/or a TLB translates virtual addresses to physical
-addresses on a CPU.  This is needed so that e.g. PCI devices can
-access with a Single Address Cycle (32bit DMA address) any page in the
-64bit physical address space.  Previously in Linux those 64bit
-platforms had to set artificial limits on the maximum RAM size in the
-system, so that the virt_to_bus() static scheme works (the DMA address
-translation tables were simply filled on bootup to map each bus
-address to the physical page __pa(bus_to_virt())).
+                       CPU and DMA addresses
+
+There are several kinds of addresses involved in the DMA API, and it's
+important to understand the differences.
+
+The kernel normally uses virtual addresses.  Any address returned by
+kmalloc(), vmalloc(), and similar interfaces is a virtual address and can
+be stored in a "void *".
+
+The virtual memory system (TLB, page tables, etc.) translates virtual
+addresses to CPU physical addresses, which are stored as "phys_addr_t" or
+"resource_size_t".  The kernel manages device resources like registers as
+physical addresses.  These are the addresses in /proc/iomem.  The physical
+address is not directly useful to a driver; it must use ioremap() to map
+the space and produce a virtual address.
+
+I/O devices use a third kind of address: a "bus address" or "DMA address".
+If a device has registers at an MMIO address, or if it performs DMA to read
+or write system memory, the addresses used by the device are bus addresses.
+In some systems, bus addresses are identical to CPU physical addresses, but
+in general they are not.  IOMMUs and host bridges can produce arbitrary
+mappings between physical and bus addresses.
+
+Here's a picture and some examples:

+
+During the enumeration process, the kernel learns about I/O devices and
+their MMIO space and the host bridges that connect them to the system.  For
+example, if a PCI device has a BAR, the kernel reads the bus address (A)
+from the BAR and converts it to a CPU physical address (B).  The address B
+is stored in a struct resource and usually exposed via /proc/iomem.  When a
+driver claims a device, it typically uses ioremap() to map physical address
+B at a virtual address (C).  It can then use, e.g., ioread32(C), to access
+the device registers at bus address A.
+
+If the device supports DMA, the driver sets up a buffer using kmalloc() or
+a similar interface, which returns a virtual address (X).  The virtual

+    <para>
+      Just like a Linux USB driver needs to register itself with the
+      Linux USB subsystem, the MUSB glue layer needs first to register
+      itself with the MUSB controller driver. This will allow the
+      controller driver to know about which device the glue layer
+      supports and which functions to call when a supported device is
+      detected or released; remember we are talking about an embedded
+      controller chip here, so no insertion or removal at run-time.
+    </para>
+    <para>
+      All of this information is passed to the MUSB controller driver
+      through a platform_driver structure defined in the glue layer as:

+      The probe and remove function pointers are called when a matching

+    <para>
+      In order to register itself to the controller driver, the glue
+      layer goes through a few steps, basically allocating the
+      controller hardware resources and initialising a couple of
+      circuits. To do so, it needs to keep track of the information used
+      throughout these steps. This is done by defining a private

+      The dev and musb members are both device structure variables. The

+      usable in a blocking situation. The PLATFORM_DEVID_AUTO flag (line
+      12) allows automatic allocation and management of device IDs in
+      order to avoid device namespace collisions with explicit IDs. With
+      devm_clk_get() (line 18) the glue layer allocates the clock -- the

+      Finally comes passing on the platform specific data to the

+      <link linkend="device-platform-data">Chapter 4</link>, but here
+      we are looking at the platform_ops function pointer (line 5) in

+    <para>
+      In order to write an MUSB glue layer, you need to have some data

+      The jz4740_udc_xceiv_device platform device structure (line 2)
+      describes the UDC transceiver with a name and id number.
+    </para>
+    <para>
+      At the time of this writing, note that
+      &quot;usb_phy_gen_xceiv&quot; is the specific name to be used for
+      all transceivers that are either built-in with reference USB IP or
+      autonomous and doesn't require any PHY programming. You will need
+      to set CONFIG_NOP_USB_XCEIV=y in the kernel configuration to make
+      use of the corresponding transceiver driver. The id field could be
+      set to -1 (equivalent to PLATFORM_DEVID_NONE), -2 (equivalent to
+      PLATFORM_DEVID_AUTO) or start with 0 for the first device of this
+      kind if we want a specific id number.
+    </para>
+    <para>
+      The jz4740_udc_resources resource structure (line 7) defines the

+    <para>
+      The first array (line 9 to 11) defines the UDC registers base
+      memory addresses: start points to the first register memory
+      address, end points to the last register memory address and the
+      flags member defines the type of resource we are dealing with. So
+      IORESOURCE_MEM is used to define the registers memory addresses.
+      The second array (line 14 to 17) defines the UDC IRQ registers
+      addresses. Since there is only one IRQ register available for the
+      JZ4740 UDC, start and end point at the same address. The
+      IORESOURCE_IRQ flag tells that we are dealing with IRQ resources,
+      and the name &quot;mc&quot; is in fact hard-coded in the MUSB core
+      in order for the controller driver to retrieve this IRQ resource
+      by querying it by its name.
+    </para>
+    <para>
+      Finally, the jz4740_udc_device platform device structure (line 21)
+      describes the UDC itself.
+    </para>
+    <para>
+      The &quot;musb-jz4740&quot; name (line 22) defines the MUSB
+      driver that is used for this device; remember this is in fact
+      the name that we used in the jz4740_driver platform driver
+      structure in <link linkend="linux-musb-basics">Chapter
+      2</link>. The id field (line 23) is set to -1 (equivalent to
+      PLATFORM_DEVID_NONE) since we do not need an id for the device:
+      the MUSB controller driver was already set to allocate an
+      automatic id in <link linkend="linux-musb-basics">Chapter
+      2</link>. In the dev field we care for DMA related information
+      here. The dma_mask field (line 25) defines the width of the DMA
+      mask that is going to be used, and coherent_dma_mask (line 26)
+      has the same purpose but for the alloc_coherent DMA mappings: in
+      both cases we are using a 32 bits mask. Then the resource field
+      (line 29) is simply a pointer to the resource structure defined
+      before, while the num_resources field (line 28) keeps track of
+      the number of arrays defined in the resource structure (in this
+      case there were two resource arrays defined before).
+    </para>
+    <para>
+      With this quick overview of the UDC platform data at the arch/

+    <programlisting linenumbering="numbered">

+    </programlisting>
+    <para>
+      First the glue layer configures some aspects of the controller

+    <para>
+      Defining the OTG capability of the controller hardware, the

+      since the JZ4740 UDC is not OTG compatible. Then num_eps (line
+      5) defines the number of USB endpoints of the controller
+      hardware, including endpoint 0: here we have 3 endpoints +
+      endpoint 0. Next is ram_bits (line 7) which is the width of the
+      RAM address bus for the MUSB controller hardware. This
+      information is needed when the controller driver cannot
+      automatically configure endpoints by reading the relevant
+      controller hardware registers. This issue will be discussed when
+      we get to device quirks in <link linkend="device-quirks">Chapter
+      5</link>. Last two fields (line 8 and 9) are also about device
+      quirks: fifo_cfg points to the USB endpoints configuration table
+      and fifo_cfg_size keeps track of the size of the number of
+      entries in that configuration table. More on that later in <link
+      linkend="device-quirks">Chapter 5</link>.
+    </para>
+    <para>
+      Then this configuration is embedded inside
+      jz4740_musb_platform_data musb_hdrc_platform_data structure (line
+      11): config is a pointer to the configuration structure itself,
+      and mode tells the controller driver if the controller hardware
+      may be used as MUSB_HOST only, MUSB_PERIPHERAL only or MUSB_OTG
+      which is a dual mode.
+    </para>
+    <para>
+      Remember that jz4740_musb_platform_data is then used to convey

+    <para>
+      Without these registers, the controller driver is unable to read

+      Looking at the configuration table above, we see that each

+      bytes at once (this is in fact a bulk in/out endpoint), and

+PROPER CARE AND FEEDING OF RETURN VALUES FROM rcu_dereference()
+
+Most of the time, you can use values from rcu_dereference() or one of
+the similar primitives without worries.  Dereferencing (prefix "*"),
+field selection ("->"), assignment ("="), address-of ("&"), addition and
+subtraction of constants, and casts all work quite naturally and safely.
+
+It is nevertheless possible to get into trouble with other operations.
+Follow these rules to keep your RCU code working properly:
+
+o	You must use one of the rcu_dereference() family of primitives
+	to load an RCU-protected pointer, otherwise CONFIG_PROVE_RCU
+	will complain.  Worse yet, your code can see random memory-corruption
+	bugs due to games that compilers and DEC Alpha can play.
+	Without one of the rcu_dereference() primitives, compilers
+	can reload the value, and won't your code have fun with two
+	different values for a single pointer!  Without rcu_dereference(),
+	DEC Alpha can load a pointer, dereference that pointer, and
+	return data preceding initialization that preceded the store of
+	the pointer.
+
+	In addition, the volatile cast in rcu_dereference() prevents the
+	compiler from deducing the resulting pointer value.  Please see
+	the section entitled "EXAMPLE WHERE THE COMPILER KNOWS TOO MUCH"
+	for an example where the compiler can in fact deduce the exact
+	value of the pointer, and thus cause misordering.
+
+o	Do not use single-element RCU-protected arrays.  The compiler
+	is within its right to assume that the value of an index into
+	such an array must necessarily evaluate to zero.  The compiler
+	could then substitute the constant zero for the computation, so
+	that the array index no longer depended on the value returned
+	by rcu_dereference().  If the array index no longer depends
+	on rcu_dereference(), then both the compiler and the CPU
+	are within their rights to order the array access before the
+	rcu_dereference(), which can cause the array access to return
+	garbage.
+
+o	Avoid cancellation when using the "+" and "-" infix arithmetic
+	operators.  For example, for a given variable "x", avoid
+	"(x-x)".  There are similar arithmetic pitfalls from other
+	arithmetic operatiors, such as "(x*0)", "(x/(x+1))" or "(x%1)".
+	The compiler is within its rights to substitute zero for all of
+	these expressions, so that subsequent accesses no longer depend
+	on the rcu_dereference(), again possibly resulting in bugs due
+	to misordering.
+
+	Of course, if "p" is a pointer from rcu_dereference(), and "a"
+	and "b" are integers that happen to be equal, the expression
+	"p+a-b" is safe because its value still necessarily depends on
+	the rcu_dereference(), thus maintaining proper ordering.
+
+o	Avoid all-zero operands to the bitwise "&" operator, and
+	similarly avoid all-ones operands to the bitwise "|" operator.
+	If the compiler is able to deduce the value of such operands,
+	it is within its rights to substitute the corresponding constant
+	for the bitwise operation.  Once again, this causes subsequent
+	accesses to no longer depend on the rcu_dereference(), causing
+	bugs due to misordering.
+
+	Please note that single-bit operands to bitwise "&" can also
+	be dangerous.  At this point, the compiler knows that the
+	resulting value can only take on one of two possible values.
+	Therefore, a very small amount of additional information will
+	allow the compiler to deduce the exact value, which again can
+	result in misordering.
+
+o	If you are using RCU to protect JITed functions, so that the
+	"()" function-invocation operator is applied to a value obtained
+	(directly or indirectly) from rcu_dereference(), you may need to
+	interact directly with the hardware to flush instruction caches.
+	This issue arises on some systems when a newly JITed function is
+	using the same memory that was used by an earlier JITed function.
+
+o	Do not use the results from the boolean "&&" and "||" when
+	dereferencing.	For example, the following (rather improbable)
+	code is buggy:
+
+		int a[2];
+		int index;
+		int force_zero_index = 1;
+
+		...
+
+		r1 = rcu_dereference(i1)
+		r2 = a[r1 && force_zero_index];  /* BUGGY!!! */
+
+	The reason this is buggy is that "&&" and "||" are often compiled
+	using branches.  While weak-memory machines such as ARM or PowerPC
+	do order stores after such branches, they can speculate loads,
+	which can result in misordering bugs.
+
+o	Do not use the results from relational operators ("==", "!=",
+	">", ">=", "<", or "<=") when dereferencing.  For example,
+	the following (quite strange) code is buggy:
+
+		int a[2];
+		int index;
+		int flip_index = 0;
+
+		...
+
+		r1 = rcu_dereference(i1)
+		r2 = a[r1 != flip_index];  /* BUGGY!!! */
+
+	As before, the reason this is buggy is that relational operators
+	are often compiled using branches.  And as before, although
+	weak-memory machines such as ARM or PowerPC do order stores
+	after such branches, but can speculate loads, which can again
+	result in misordering bugs.
+
+o	Be very careful about comparing pointers obtained from
+	rcu_dereference() against non-NULL values.  As Linus Torvalds
+	explained, if the two pointers are equal, the compiler could
+	substitute the pointer you are comparing against for the pointer
+	obtained from rcu_dereference().  For example:
+
+		p = rcu_dereference(gp);
+		if (p == &default_struct)
+			do_default(p->a);
+
+	Because the compiler now knows that the value of "p" is exactly
+	the address of the variable "default_struct", it is free to
+	transform this code into the following:
+
+		p = rcu_dereference(gp);
+		if (p == &default_struct)
+			do_default(default_struct.a);
+
+	On ARM and Power hardware, the load from "default_struct.a"
+	can now be speculated, such that it might happen before the
+	rcu_dereference().  This could result in bugs due to misordering.
+
+	However, comparisons are OK in the following cases:
+
+	o	The comparison was against the NULL pointer.  If the
+		compiler knows that the pointer is NULL, you had better
+		not be dereferencing it anyway.  If the comparison is
+		non-equal, the compiler is none the wiser.  Therefore,
+		it is safe to compare pointers from rcu_dereference()
+		against NULL pointers.
+
+	o	The pointer is never dereferenced after being compared.
+		Since there are no subsequent dereferences, the compiler
+		cannot use anything it learned from the comparison
+		to reorder the non-existent subsequent dereferences.
+		This sort of comparison occurs frequently when scanning
+		RCU-protected circular linked lists.
+
+	o	The comparison is against a pointer that references memory
+		that was initialized "a long time ago."  The reason
+		this is safe is that even if misordering occurs, the
+		misordering will not affect the accesses that follow
+		the comparison.  So exactly how long ago is "a long
+		time ago"?  Here are some possibilities:
+
+		o	Compile time.
+
+		o	Boot time.
+
+		o	Module-init time for module code.
+
+		o	Prior to kthread creation for kthread code.
+
+		o	During some prior acquisition of the lock that
+			we now hold.
+
+		o	Before mod_timer() time for a timer handler.
+
+		There are many other possibilities involving the Linux
+		kernel's wide array of primitives that cause code to
+		be invoked at a later time.
+
+	o	The pointer being compared against also came from
+		rcu_dereference().  In this case, both pointers depend
+		on one rcu_dereference() or another, so you get proper
+		ordering either way.
+
+		That said, this situation can make certain RCU usage
+		bugs more likely to happen.  Which can be a good thing,
+		at least if they happen during testing.  An example
+		of such an RCU usage bug is shown in the section titled
+		"EXAMPLE OF AMPLIFIED RCU-USAGE BUG".
+
+	o	All of the accesses following the comparison are stores,
+		so that a control dependency preserves the needed ordering.
+		That said, it is easy to get control dependencies wrong.
+		Please see the "CONTROL DEPENDENCIES" section of
+		Documentation/memory-barriers.txt for more details.
+
+	o	The pointers are not equal -and- the compiler does
+		not have enough information to deduce the value of the
+		pointer.  Note that the volatile cast in rcu_dereference()
+		will normally prevent the compiler from knowing too much.
+
+o	Disable any value-speculation optimizations that your compiler
+	might provide, especially if you are making use of feedback-based
+	optimizations that take data collected from prior runs.  Such
+	value-speculation optimizations reorder operations by design.
+
+	There is one exception to this rule:  Value-speculation
+	optimizations that leverage the branch-prediction hardware are
+	safe on strongly ordered systems (such as x86), but not on weakly
+	ordered systems (such as ARM or Power).  Choose your compiler
+	command-line options wisely!
+
+
+EXAMPLE OF AMPLIFIED RCU-USAGE BUG
+
+Because updaters can run concurrently with RCU readers, RCU readers can
+see stale and/or inconsistent values.  If RCU readers need fresh or
+consistent values, which they sometimes do, they need to take proper
+precautions.  To see this, consider the following code fragment:
+
+	struct foo {
+		int a;
+		int b;
+		int c;
+	};
+	struct foo *gp1;
+	struct foo *gp2;
+
+	void updater(void)
+	{
+		struct foo *p;
+
+		p = kmalloc(...);
+		if (p == NULL)
+			deal_with_it();
+		p->a = 42;  /* Each field in its own cache line. */
+		p->b = 43;
+		p->c = 44;
+		rcu_assign_pointer(gp1, p);
+		p->b = 143;
+		p->c = 144;
+		rcu_assign_pointer(gp2, p);
+	}
+
+	void reader(void)
+	{
+		struct foo *p;
+		struct foo *q;
+		int r1, r2;
+
+		p = rcu_dereference(gp2);
+		if (p == NULL)
+			return;
+		r1 = p->b;  /* Guaranteed to get 143. */
+		q = rcu_dereference(gp1);  /* Guaranteed non-NULL. */
+		if (p == q) {
+			/* The compiler decides that q->c is same as p->c. */
+			r2 = p->c; /* Could get 44 on weakly order system. */
+		}
+		do_something_with(r1, r2);
+	}
+
+You might be surprised that the outcome (r1 == 143 && r2 == 44) is possible,
+but you should not be.  After all, the updater might have been invoked
+a second time between the time reader() loaded into "r1" and the time
+that it loaded into "r2".  The fact that this same result can occur due
+to some reordering from the compiler and CPUs is beside the point.
+
+But suppose that the reader needs a consistent view?
+
+Then one approach is to use locking, for example, as follows:
+
+	struct foo {
+		int a;
+		int b;
+		int c;
+		spinlock_t lock;
+	};
+	struct foo *gp1;
+	struct foo *gp2;
+
+	void updater(void)
+	{
+		struct foo *p;
+
+		p = kmalloc(...);
+		if (p == NULL)
+			deal_with_it();
+		spin_lock(&p->lock);
+		p->a = 42;  /* Each field in its own cache line. */
+		p->b = 43;
+		p->c = 44;
+		spin_unlock(&p->lock);
+		rcu_assign_pointer(gp1, p);
+		spin_lock(&p->lock);
+		p->b = 143;
+		p->c = 144;
+		spin_unlock(&p->lock);
+		rcu_assign_pointer(gp2, p);
+	}
+
+	void reader(void)
+	{
+		struct foo *p;
+		struct foo *q;
+		int r1, r2;
+
+		p = rcu_dereference(gp2);
+		if (p == NULL)
+			return;
+		spin_lock(&p->lock);
+		r1 = p->b;  /* Guaranteed to get 143. */
+		q = rcu_dereference(gp1);  /* Guaranteed non-NULL. */
+		if (p == q) {
+			/* The compiler decides that q->c is same as p->c. */
+			r2 = p->c; /* Locking guarantees r2 == 144. */
+		}
+		spin_unlock(&p->lock);
+		do_something_with(r1, r2);
+	}
+
+As always, use the right tool for the job!
+
+
+EXAMPLE WHERE THE COMPILER KNOWS TOO MUCH
+
+If a pointer obtained from rcu_dereference() compares not-equal to some
+other pointer, the compiler normally has no clue what the value of the
+first pointer might be.  This lack of knowledge prevents the compiler
+from carrying out optimizations that otherwise might destroy the ordering
+guarantees that RCU depends on.  And the volatile cast in rcu_dereference()
+should prevent the compiler from guessing the value.
+
+But without rcu_dereference(), the compiler knows more than you might
+expect.  Consider the following code fragment:
+
+	struct foo {
+		int a;
+		int b;
+	};
+	static struct foo variable1;
+	static struct foo variable2;
+	static struct foo *gp = &variable1;
+
+	void updater(void)
+	{
+		initialize_foo(&variable2);
+		rcu_assign_pointer(gp, &variable2);
+		/*
+		 * The above is the only store to gp in this translation unit,
+		 * and the address of gp is not exported in any way.
+		 */
+	}
+
+	int reader(void)
+	{
+		struct foo *p;
+
+		p = gp;
+		barrier();
+		if (p == &variable1)
+			return p->a; /* Must be variable1.a. */
+		else
+			return p->b; /* Must be variable2.b. */
+	}
+
+Because the compiler can see all stores to "gp", it knows that the only
+possible values of "gp" are "variable1" on the one hand and "variable2"
+on the other.  The comparison in reader() therefore tells the compiler
+the exact value of "p" even in the not-equals case.  This allows the
+compiler to make the return values independent of the load from "gp",
+in turn destroying the ordering between this load and the loads of the
+return values.  This can result in "p->b" returning pre-initialization
+garbage values.
+
+In short, rcu_dereference() is -not- optional when you are going to
+dereference the resulting pointer.

+Marvell Berlin SoCs have a chip control register set providing several

+- reg: address and length of the system control register set

+
+As clock related registers are spread among the chip control registers, the
+chip control node also provides the clocks. Marvell Berlin2 (BG2, BG2CD, BG2Q)
+SoCs share the same IP for PLLs and clocks, with some minor differences in
+features and register layout.
+
+Required properties:
+- #clock-cells: shall be set to 1
+- clocks: clock specifiers referencing the core clock input clocks
+- clock-names: array of strings describing the input clock specifiers above.
+    Allowed clock-names for the reference clocks are

+    and SoC-specific input clocks for
+      BG2/BG2CD: "video_ext0" for the external video clock input
+
+Clocks provided by core clocks shall be referenced by a clock specifier
+indexing one of the provided clocks. Refer to dt-bindings/clock/berlin<soc>.h
+for the corresponding index mapping.
+
+* Pin controller binding
+
+Pin control registers are part of both register sets, chip control and system
+control. The pins controlled are organized in groups, so no actual pin
+information is needed.
+
+A pin-controller node should contain subnodes representing the pin group
+configurations, one per function. Each subnode has the group name and the muxing
+function used.
+
+Be aware the Marvell Berlin datasheets use the keyword 'mode' for what is called
+a 'function' in the pin-controller subsystem.
+
+Required subnode-properties:
+- groups: a list of strings describing the group names.
+- function: a string describing the function used to mux the groups.

+* Samsung Exynos5260 Clock Controller
+
+Exynos5260 has 13 clock controllers which are instantiated
+independently from the device-tree. These clock controllers
+generate and supply clocks to various hardware blocks within
+the SoC.
+
+Each clock is assigned an identifier and client nodes can use
+this identifier to specify the clock which they consume. All
+available clocks are defined as preprocessor macros in
+dt-bindings/clock/exynos5260-clk.h header and can be used in
+device tree sources.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It
+is expected that they are defined using standard clock bindings
+with following clock-output-names:
+
+ - "fin_pll" - PLL input clock from XXTI
+ - "xrtcxti" - input clock from XRTCXTI
+ - "ioclk_pcm_extclk" - pcm external operation clock
+ - "ioclk_spdif_extclk" - spdif external operation clock
+ - "ioclk_i2s_cdclk" - i2s0 codec clock
+
+Phy clocks:
+
+There are several clocks which are generated by specific PHYs.
+These clocks are fed into the clock controller and then routed to
+the hardware blocks. These clocks are defined as fixed clocks in the
+driver with following names:
+
+ - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
+ - "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
+ - "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
+ - "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
+ - "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
+ - "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
+ - "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
+ - "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
+ - "phyclk_dptx_phy_clk_div2"
+ - "phyclk_mipi_dphy_4l_m_rxclkesc0"
+ - "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock

+* Generic PCI host controller
+
+Firmware-initialised PCI host controllers and PCI emulations, such as the
+virtio-pci implementations found in kvmtool and other para-virtualised
+systems, do not require driver support for complexities such as regulator
+and clock management. In fact, the controller may not even require the
+configuration of a control interface by the operating system, instead
+presenting a set of fixed windows describing a subset of IO, Memory and
+Configuration Spaces.
+
+Such a controller can be described purely in terms of the standardized device
+tree bindings communicated in pci.txt:
+
+
+Properties of the host controller node:
+
+- compatible     : Must be "pci-host-cam-generic" or "pci-host-ecam-generic"
+                   depending on the layout of configuration space (CAM vs
+                   ECAM respectively).
+
+- device_type    : Must be "pci".
+
+- ranges         : As described in IEEE Std 1275-1994, but must provide
+                   at least a definition of non-prefetchable memory. One
+                   or both of prefetchable Memory and IO Space may also
+                   be provided.
+
+- bus-range      : Optional property (also described in IEEE Std 1275-1994)
+                   to indicate the range of bus numbers for this controller.
+                   If absent, defaults to <0 255> (i.e. all buses).
+
+- #address-cells : Must be 3.
+
+- #size-cells    : Must be 2.
+
+- reg            : The Configuration Space base address and size, as accessed
+                   from the parent bus.
+
+
+Properties of the /chosen node:
+
+- linux,pci-probe-only
+                 : Optional property which takes a single-cell argument.
+                   If '0', then Linux will assign devices in its usual manner,
+                   otherwise it will not try to assign devices and instead use
+                   them as they are configured already.
+
+Configuration Space is assumed to be memory-mapped (as opposed to being
+accessed via an ioport) and laid out with a direct correspondence to the
+geography of a PCI bus address by concatenating the various components to
+form an offset.
+
+For CAM, this 24-bit offset is:
+
+        cfg_offset(bus, device, function, register) =
+                   bus << 16 | device << 11 | function << 8 | register
+
+Whilst ECAM extends this by 4 bits to accomodate 4k of function space:
+
+        cfg_offset(bus, device, function, register) =
+                   bus << 20 | device << 15 | function << 12 | register
+
+Interrupt mapping is exactly as described in `Open Firmware Recommended
+Practice: Interrupt Mapping' and requires the following properties:
+
+- #interrupt-cells   : Must be 1
+
+- interrupt-map      : <see aforementioned specification>
+
+- interrupt-map-mask : <see aforementioned specification>
+
+
+Example:
+
+pci {
+    compatible = "pci-host-cam-generic"
+    device_type = "pci";
+    #address-cells = <3>;
+    #size-cells = <2>;
+    bus-range = <0x0 0x1>;
+
+    // CPU_PHYSICAL(2)  SIZE(2)
+    reg = <0x0 0x40000000  0x0 0x1000000>;
+
+    // BUS_ADDRESS(3)  CPU_PHYSICAL(2)  SIZE(2)
+    ranges = <0x01000000 0x0 0x01000000  0x0 0x01000000  0x0 0x00010000>,

+
+
+    #interrupt-cells = <0x1>;
+

+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+                The first cell is the gpio pin number and the

+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Qualcomm's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength,
+ output-low, output-high.
+
+Non-empty subnodes must specify the 'pins' property.
+
+Valid values for pins are:
+  gpio0-gpio89
+
+Valid values for function are:
+  cam_mclk, codec_mic_i2s, codec_spkr_i2s, gsbi1, gsbi2, gsbi3, gsbi4,
+  gsbi4_cam_i2c, gsbi5, gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6,

+* Device tree bindings for Texas Instruments keystone reset
+
+This node is intended to allow SoC reset in case of software reset
+of selected watchdogs.
+
+The Keystone SoCs can contain up to 4 watchdog timers to reset
+SoC. Each watchdog timer event input is connected to the Reset Mux
+block. The Reset Mux block can be configured to cause reset or not.
+
+Additionally soft or hard reset can be configured.
+
+Required properties:
+
+- compatible:		ti,keystone-reset

+- ti,syscon-pll:	phandle/offset pair. The phandle to syscon used to
+			access pll controller registers and the offset to use
+			reset control registers.
+
+- ti,syscon-dev:	phandle/offset pair. The phandle to syscon used to
+			access device state control registers and the offset
+			in order to use mux block registers for all watchdogs.
+
+Optional properties:
+
+- ti,soft-reset:	Boolean option indicating soft reset.
+			By default hard reset is used.
+
+- ti,wdt-list:		WDT list that can cause SoC reset. It's not related
+			to WDT driver, it's just needed to enable a SoC related
+			reset that's triggered by one of WDTs. The list is
+			in format: <0>, <2>; It can be in random order and
+			begins from 0 to 3, as keystone can contain up to 4 SoC
+			reset watchdogs and can be in random order.
+
+Example 1:
+Setup keystone reset so that in case software reset or
+WDT0 is triggered it issues hard reset for SoC.
+

+
+Required properties:

+  ldo1, ldo2, ldo3, and ldo4, specifying the initialization data as
+  documented in Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Each regulator is defined using the standard binding for regulators. The
+nodes for sw1, sw2, sw3, bb-out, ldo1, and ldo2 additionally need to specify
+the resistor values of their external feedback voltage dividers:
+
+Required properties (not on ldo3, ldo4):
+- lltc,fb-voltage-divider: An array of two integers containing the resistor
+  values R1 and R2 of the feedback voltage divider in ohms.
+
+Regulators sw1, sw2, sw3, and ldo2 can regulate the feedback reference from
+0.3625 V to 0.75 V in 12.5 mV steps. The output voltage thus ranges between
+0.3625 * (1 + R1/R2) V and 0.75 * (1 + R1/R2) V. Regulators bb-out and ldo1
+have a fixed 0.8 V reference and thus output 0.8 * (1 + R1/R2) V. The ldo3
+regulator is fixed to 1.8 V on LTC3589 and to 2.8 V on LTC3589-1,2. The ldo4
+regulator can output between 1.8 V and 3.3 V on LTC3589 and between 1.2 V
+and 3.2 V on LTC3589-1,2 in four steps. The ldo1 standby regulator can not
+be disabled and thus should have the regulator-always-on property set.

@@ -73,6 +73,65 @@ The IRQ portions of the GPIO block are implemented using an irqchip, using
 the header <linux/irq.h>. So basically such a driver is utilizing two sub-
 systems simultaneously: gpio and irq.
 
+GPIO irqchips usually fall in one of two categories:
+
+* CHAINED GPIO irqchips: these are usually the type that is embedded on
+  an SoC. This means that there is a fast IRQ handler for the GPIOs that
+  gets called in a chain from the parent IRQ handler, most typically the
+  system interrupt controller. This means the GPIO irqchip is registered
+  using irq_set_chained_handler() or the corresponding
+  gpiochip_set_chained_irqchip() helper function, and the GPIO irqchip
+  handler will be called immediately from the parent irqchip, while
+  holding the IRQs disabled. The GPIO irqchip will then end up calling
+  something like this sequence in its interrupt handler:
+
+  static irqreturn_t tc3589x_gpio_irq(int irq, void *data)
+      chained_irq_enter(...);
+      generic_handle_irq(...);
+      chained_irq_exit(...);
+
+  Chained GPIO irqchips typically can NOT set the .can_sleep flag on
+  struct gpio_chip, as everything happens directly in the callbacks.
+
+* NESTED THREADED GPIO irqchips: these are off-chip GPIO expanders and any
+  other GPIO irqchip residing on the other side of a sleeping bus. Of course
+  such drivers that need slow bus traffic to read out IRQ status and similar,
+  traffic which may in turn incur other IRQs to happen, cannot be handled
+  in a quick IRQ handler with IRQs disabled. Instead they need to spawn a
+  thread and then mask the parent IRQ line until the interrupt is handled
+  by the driver. The hallmark of this driver is to call something like
+  this in its interrupt handler:
+
+  static irqreturn_t tc3589x_gpio_irq(int irq, void *data)
+      ...
+      handle_nested_irq(irq);
+
+  The hallmark of threaded GPIO irqchips is that they set the .can_sleep
+  flag on struct gpio_chip to true, indicating that this chip may sleep
+  when accessing the GPIOs.
+
+To help out in handling the set-up and management of GPIO irqchips and the
+associated irqdomain and resource allocation callbacks, the gpiolib has
+some helpers that can be enabled by selecting the GPIOLIB_IRQCHIP Kconfig
+symbol:
+
+* gpiochip_irqchip_add(): adds an irqchip to a gpiochip. It will pass
+  the struct gpio_chip* for the chip to all IRQ callbacks, so the callbacks
+  need to embed the gpio_chip in its state container and obtain a pointer
+  to the container using container_of().
+  (See Documentation/driver-model/design-patterns.txt)
+
+* gpiochip_set_chained_irqchip(): sets up a chained irq handler for a
+  gpio_chip from a parent IRQ and passes the struct gpio_chip* as handler
+  data. (Notice handler data, since the irqchip data is likely used by the
+  parent irqchip!) This is for the chained type of chip.
+
+To use the helpers please keep the following in mind:
+
+- Make sure to assign all relevant members of the struct gpio_chip so that
+  the irqchip can initialize. E.g. .dev and .can_sleep shall be set up
+  properly.
+
 It is legal for any IRQ consumer to request an IRQ from any irqchip no matter
 if that is a combined GPIO+IRQ driver. The basic premise is that gpio_chip and
 irq_chip are orthogonal, and offering their services independent of each

+HSI - High-speed Synchronous Serial Interface
+
+1. Introduction
+~~~~~~~~~~~~~~~
+
+High Speed Syncronous Interface (HSI) is a fullduplex, low latency protocol,
+that is optimized for die-level interconnect between an Application Processor
+and a Baseband chipset. It has been specified by the MIPI alliance in 2003 and
+implemented by multiple vendors since then.
+
+The HSI interface supports full duplex communication over multiple channels
+(typically 8) and is capable of reaching speeds up to 200 Mbit/s.
+
+The serial protocol uses two signals, DATA and FLAG as combined data and clock
+signals and an additional READY signal for flow control. An additional WAKE
+signal can be used to wakeup the chips from standby modes. The signals are
+commonly prefixed by AC for signals going from the application die to the
+cellular die and CA for signals going the other way around.

+2. HSI Subsystem in Linux
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the Linux kernel the hsi subsystem is supposed to be used for HSI devices.
+The hsi subsystem contains drivers for hsi controllers including support for
+multi-port controllers and provides a generic API for using the HSI ports.
+
+It also contains HSI client drivers, which make use of the generic API to
+implement a protocol used on the HSI interface. These client drivers can
+use an arbitrary number of channels.
+
+3. hsi-char Device
+~~~~~~~~~~~~~~~~~~
+
+Each port automatically registers a generic client driver called hsi_char,
+which provides a charecter device for userspace representing the HSI port.
+It can be used to communicate via HSI from userspace. Userspace may
+configure the hsi_char device using the following ioctl commands:
+
+* HSC_RESET:
+ - flush the HSI port
+
+* HSC_SET_PM
+ - enable or disable the client.
+
+* HSC_SEND_BREAK
+ - send break
+
+* HSC_SET_RX
+ - set RX configuration
+
+* HSC_GET_RX
+ - get RX configuration

+* HSC_SET_TX

+Description
+-----------
+
+The Standard Microsystems Corporation (SMSC) / Microchip EMC14xx chips
+contain up to four temperature sensors. EMC14x2 support two sensors
+(one internal, one external). EMC14x3 support three sensors (one internal,
+two external), and EMC14x4 support four sensors (one internal, three
+external).
+
+The chips implement three limits for each sensor: low (tempX_min), high
+(tempX_max) and critical (tempX_crit.) The chips also implement an
+hysteresis mechanism which applies to all limits. The relative difference
+is stored in a single register on the chip, which means that the relative
+difference between the limit and its hysteresis is always the same for
+all three limits.
+
+This implementation detail implies the following:
+* When setting a limit, its hysteresis will automatically follow, the
+  difference staying unchanged. For example, if the old critical limit
+  was 80 degrees C, and the hysteresis was 75 degrees C, and you change
+  the critical limit to 90 degrees C, then the hysteresis will
+  automatically change to 85 degrees C.
+* The hysteresis values can't be set independently. We decided to make
+  only temp1_crit_hyst writable, while all other hysteresis attributes
+  are read-only. Setting temp1_crit_hyst writes the difference between
+  temp1_crit_hyst and temp1_crit into the chip, and the same relative
+  hysteresis applies automatically to all other limits.
+* The limits should be set before the hysteresis.

+The Linux Hardware Monitoring kernel API.
+=========================================
+
+Guenter Roeck
+
+Introduction
+------------
+
+This document describes the API that can be used by hardware monitoring
+drivers that want to use the hardware monitoring framework.
+
+This document does not describe what a hardware monitoring (hwmon) Driver or
+Device is. It also does not describe the API which can be used by user space
+to communicate with a hardware monitoring device. If you want to know this
+then please read the following file: Documentation/hwmon/sysfs-interface.
+
+For additional guidelines on how to write and improve hwmon drivers, please
+also read Documentation/hwmon/submitting-patches.
+
+The API
+-------
+Each hardware monitoring driver must #include <linux/hwmon.h> and, in most
+cases, <linux/hwmon-sysfs.h>. linux/hwmon.h declares the following
+register/unregister functions:
+
+struct device *hwmon_device_register(struct device *dev);
+struct device *
+hwmon_device_register_with_groups(struct device *dev, const char *name,
+				  void *drvdata,
+				  const struct attribute_group **groups);
+
+struct device *
+devm_hwmon_device_register_with_groups(struct device *dev,
+				       const char *name, void *drvdata,
+				       const struct attribute_group **groups);
+
+void hwmon_device_unregister(struct device *dev);
+void devm_hwmon_device_unregister(struct device *dev);
+
+hwmon_device_register registers a hardware monitoring device. The parameter
+of this function is a pointer to the parent device.
+This function returns a pointer to the newly created hardware monitoring device
+or PTR_ERR for failure. If this registration function is used, hardware
+monitoring sysfs attributes are expected to have been created and attached to
+the parent device prior to calling hwmon_device_register. A name attribute must
+have been created by the caller.
+
+hwmon_device_register_with_groups is similar to hwmon_device_register. However,
+it has additional parameters. The name parameter is a pointer to the hwmon
+device name. The registration function wil create a name sysfs attribute
+pointing to this name. The drvdata parameter is the pointer to the local
+driver data.  hwmon_device_register_with_groups will attach this pointer
+to the newly allocated hwmon device. The pointer can be retrieved by the driver
+using dev_get_drvdata() on the hwmon device pointer. The groups parameter is
+a pointer to a list of sysfs attribute groups. The list must be NULL terminated.
+hwmon_device_register_with_groups creates the hwmon device with name attribute
+as well as all sysfs attributes attached to the hwmon device.
+
+devm_hwmon_device_register_with_groups is similar to
+hwmon_device_register_with_groups. However, it is device managed, meaning the
+hwmon device does not have to be removed explicitly by the removal function.
+
+hwmon_device_unregister deregisters a registered hardware monitoring device.
+The parameter of this function is the pointer to the registered hardware
+monitoring device structure. This function must be called from the driver
+remove function if the hardware monitoring device was registered with
+hwmon_device_register or with hwmon_device_register_with_groups.
+
+devm_hwmon_device_unregister does not normally have to be called. It is only
+needed for error handling, and only needed if the driver probe fails after
+the call to devm_hwmon_device_register_with_groups.
+
+The header file linux/hwmon-sysfs.h provides a number of useful macros to
+declare and use hardware monitoring sysfs attributes.
+
+In many cases, you can use the exsting define DEVICE_ATTR to declare such
+attributes. This is feasible if an attribute has no additional context. However,
+in many cases there will be additional information such as a sensor index which
+will need to be passed to the sysfs attribute handling function.
+
+SENSOR_DEVICE_ATTR and SENSOR_DEVICE_ATTR_2 can be used to define attributes
+which need such additional context information. SENSOR_DEVICE_ATTR requires
+one additional argument, SENSOR_DEVICE_ATTR_2 requires two.
+
+SENSOR_DEVICE_ATTR defines a struct sensor_device_attribute variable.
+This structure has the following fields.
+
+struct sensor_device_attribute {
+	struct device_attribute dev_attr;
+	int index;
+};
+
+You can use to_sensor_dev_attr to get the pointer to this structure from the
+attribute read or write function. Its parameter is the device to which the
+attribute is attached.
+
+SENSOR_DEVICE_ATTR_2 defines a struct sensor_device_attribute_2 variable,
+which is defined as follows.
+
+struct sensor_device_attribute_2 {
+	struct device_attribute dev_attr;
+	u8 index;
+	u8 nr;
+};
+
+Use to_sensor_dev_attr_2 to get the pointer to this structure. Its parameter
+is the device to which the attribute is attached.

+Description
+-----------
+
+This driver implements support for the Nuvoton NCT6683D eSIO chip.
+
+The chips implement up to shared 32 temperature and voltage sensors.
+It supports up to 16 fan rotation sensors and up to 8 fan control engines.
+
+Temperatures are measured in degrees Celsius. Measurement resolution is
+0.5 degrees C.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+
+Fan rotation speeds are reported in RPM (rotations per minute).
+
+Usage Note
+----------
+
+Limit register locations on Intel boards with EC firmware version 1.0
+build date 04/03/13 do not match the register locations in the Nuvoton
+datasheet. Nuvoton confirms that Intel uses a special firmware version
+with different register addresses. The specification describing the Intel
+firmware is held under NDA by Nuvoton and Intel and not available
+to the public.
+
+Some of the register locations can be reverse engineered; others are too
+well hidden. Given this, writing any values from the operating system is
+considered too risky with this firmware and has been disabled. All limits
+must all be written from the BIOS.
+
+The driver has only been tested with the Intel firmware, and by default
+only instantiates on Intel boards. To enable it on non-Intel boards,
+set the 'force' module parameter to 1.

+-----------------------------------
+To show how to demo OTG HNP and SRP functions via sys input files
+with 2 Freescale i.MX6Q sabre SD boards.
+
+1.1 How to enable OTG FSM in menuconfig
+---------------------------------------
+Select CONFIG_USB_OTG_FSM, rebuild kernel Image and modules.
+If you want to check some internal variables for otg fsm,
+select CONFIG_USB_CHIPIDEA_DEBUG, there are 2 files which
+can show otg fsm variables and some controller registers value:
+cat /sys/kernel/debug/ci_hdrc.0/otg
+cat /sys/kernel/debug/ci_hdrc.0/registers
+
+1.2 Test operations
+-------------------
+1) Power up 2 Freescale i.MX6Q sabre SD boards with gadget class driver loaded
+   (e.g. g_mass_storage).
+
+2) Connect 2 boards with usb cable with one end is micro A plug, the other end
+   is micro B plug.
+
+   The A-device(with micro A plug inserted) should enumrate B-device.
+
+3) Role switch

+   echo 0 > /sys/bus/platform/devices/ci_hdrc.0/inputs/b_bus_req
+
+   A-device should switch back to host and enumrate B-device.
+
+5) Remove B-device(unplug micro B plug) and insert again in 10 seconds,
+   A-device should enumrate B-device again.

+ * kvm_s390_inject_prog_cond - conditionally inject a program check
+ * @vcpu: virtual cpu
+ * @rc: original return/error code
+ *
+ * This function is supposed to be used after regular guest access functions
+ * failed, to conditionally inject a program check to a vcpu. The typical
+ * pattern would look like
+ *
+ * rc = write_guest(vcpu, addr, data, len);
+ * if (rc)
+ *	return kvm_s390_inject_prog_cond(vcpu, rc);
+ *
+ * A negative return code from guest access functions implies an internal error
+ * like e.g. out of memory. In these cases no program check should be injected
+ * to the guest.
+ * A positive value implies that an exception happened while accessing a guest's
+ * memory. In this case all data belonging to the corresponding program check
+ * has been stored in vcpu->arch.pgm and can be injected with
+ * kvm_s390_inject_prog_irq().
+ *
+ * Returns: - the original @rc value if @rc was negative (internal error)
+ *	    - zero if @rc was already zero
+ *	    - zero or error code from injecting if @rc was positive
+ *	      (program check injected to @vcpu)

+ *    logged in the bitmap, that means the page in the dirty bitmap is not
+ *    missed, so it can flush tlb out of mmu-lock.
+ *
+ * So, there is the problem: the first case can meet the corrupted tlb caused
+ * by another case which write-protects pages but without flush tlb
+ * immediately. In order to making the first case be aware this problem we let

+ * The CMT comes in 5 different identified flavours, depending not only on the
+ * SoC but also on the particular instance. The following table lists the main
+ * characteristics of those flavours.
+ *
+ *			16B	32B	32B-F	48B	48B-2
+ * -----------------------------------------------------------------------------
+ * Channels		2	1/4	1	6	2/8
+ * Control Width	16	16	16	16	32
+ * Counter Width	16	32	32	32/48	32/48
+ * Shared Start/Stop	Y	Y	Y	Y	N
+ *
+ * The 48-bit gen2 version has a per-channel start/stop register located in the
+ * channel registers block. All other versions have a shared start/stop register
+ * located in the global space.
+ *
+ * Channels are indexed from 0 to N-1 in the documentation. The channel index
+ * infers the start/stop bit position in the control register and the channel
+ * registers block address. Some CMT instances have a subset of channels
+ * available, in which case the index in the documentation doesn't match the
+ * "real" index as implemented in hardware. This is for instance the case with
+ * CMT0 on r8a7740, which is a 32-bit variant with a single channel numbered 0
+ * in the documentation but using start/stop bit 5 and having its registers
+ * block at 0x60.
+ *
+ * Similarly CMT0 on r8a73a4, r8a7790 and r8a7791, while implementing 32-bit
+ * channels only, is a 48-bit gen2 CMT with the 48-bit channels unavailable.

+**
+** Interface declarations and internal definitions for Skein hashing.
+**
+** Source code author: Doug Whiting, 2008.
+**
+** This algorithm and source code is released to the public domain.
+**
+***************************************************************************
+**
+** The following compile-time switches may be defined to control some
+** tradeoffs between speed, code size, error checking, and security.
+**
+** The "default" note explains what happens when the switch is not defined.
+**
+**  SKEIN_DEBUG            -- make callouts from inside Skein code
+**                            to examine/display intermediate values.
+**                            [default: no callouts (no overhead)]
+**
+**  SKEIN_ERR_CHECK        -- how error checking is handled inside Skein
+**                            code. If not defined, most error checking
+**                            is disabled (for performance). Otherwise,
+**                            the switch value is interpreted as:
+**                                0: use assert()      to flag errors
+**                                1: return SKEIN_FAIL to flag errors

+/**
+ * @file skein_api.h
+ * @brief A Skein API and its functions.
+ * @{
+ *
+ * This API and the functions that implement this API simplify the usage
+ * of Skein. The design and the way to use the functions follow the openSSL
+ * design but at the same time take care of some Skein specific behaviour
+ * and possibilities.
+ *
+ * The functions enable applications to create a normal Skein hashes and
+ * message authentication codes (MAC).
+ *
+ * Using these functions is simple and straight forward:
+ *
+ * @code
+ *
+ * #include "skein_api.h"
+ *
+ * ...
+ * struct skein_ctx ctx;             // a Skein hash or MAC context
+ *
+ * // prepare context, here for a Skein with a state size of 512 bits.
+ * skein_ctx_prepare(&ctx, SKEIN_512);
+ *
+ * // Initialize the context to set the requested hash length in bits
+ * // here request a output hash size of 31 bits (Skein supports variable
+ * // output sizes even very strange sizes)
+ * skein_init(&ctx, 31);
+ *
+ * // Now update Skein with any number of message bits. A function that
+ * // takes a number of bytes is also available.
+ * skein_update_bits(&ctx, message, msg_length);
+ *
+ * // Now get the result of the Skein hash. The output buffer must be
+ * // large enough to hold the request number of output bits. The application
+ * // may now extract the bits.
+ * skein_final(&ctx, result);
+ * ...
+ * @endcode
+ *
+ * An application may use @c skein_reset to reset a Skein context and use
+ * it for creation of another hash with the same Skein state size and output
+ * bit length. In this case the API implementation restores some internal
+ * internal state data and saves a full Skein initialization round.
+ *
+ * To create a MAC the application just uses @c skein_mac_init instead of
+ * @c skein_init. All other functions calls remain the same.
+ *

+ * @{
+ *
+ * This API and the functions that implement this API simplify the usage
+ * of the Threefish cipher. The design and the way to use the functions
+ * follow the openSSL design but at the same time take care of some Threefish
+ * specific behaviour and possibilities.
+ *
+ * These are the low level functions that deal with Threefish blocks only.
+ * Implementations for cipher modes such as ECB, CFB, or CBC may use these
+ * functions.

+ * Author: David Mosberger-Tang <davidm@egauge.net>
+ *

+ *
+ * MAX3421 is a chip implementing a USB 2.0 Full-/Low-Speed host
+ * controller on a SPI bus.
+ *
+ * Based on:
+ *	o MAX3421E datasheet
+ *		http://datasheets.maximintegrated.com/en/ds/MAX3421E.pdf
+ *	o MAX3421E Programming Guide
+ *		http://www.hdl.co.jp/ftpdata/utl-001/AN3785.pdf
+ *	o gadget/dummy_hcd.c
+ *		For USB HCD implementation.
+ *	o Arduino MAX3421 driver
+ *	     https://github.com/felis/USB_Host_Shield_2.0/blob/master/Usb.cpp
+ *
+ * This file is licenced under the GPL v2.
+ *
+ * Important note on worst-case (full-speed) packet size constraints
+ * (See USB 2.0 Section 5.6.3 and following):
+ *
+ *	- control:	  64 bytes
+ *	- isochronous:	1023 bytes
+ *	- interrupt:	  64 bytes
+ *	- bulk:		  64 bytes
+ *
+ * Since the MAX3421 FIFO size is 64 bytes, we do not have to work about
+ * multi-FIFO writes/reads for a single USB packet *except* for isochronous
+ * transfers.  We don't support isochronous transfers at this time, so we
+ * just assume that a USB packet always fits into a single FIFO buffer.
+ *
+ * NOTE: The June 2006 version of "MAX3421E Programming Guide"
+ * (AN3785) has conflicting info for the RCVDAVIRQ bit:
+ *
+ *	The description of RCVDAVIRQ says "The CPU *must* clear
+ *	this IRQ bit (by writing a 1 to it) before reading the
+ *	RCVFIFO data.
+ *
+ * However, the earlier section on "Programming BULK-IN
+ * Transfers" says * that:
+ *
+ *	After the CPU retrieves the data, it clears the
+ *	RCVDAVIRQ bit.
+ *
+ * The December 2006 version has been corrected and it consistently
+ * states the second behavior is the correct one.
+ *
+ * Synchronous SPI transactions sleep so we can't perform any such
+ * transactions while holding a spin-lock (and/or while interrupts are
+ * masked).  To achieve this, all SPI transactions are issued from a
+ * single thread (max3421_spi_thread).

-\-\-sched\-smt utilizes thread siblings of one processor core first before

-The impact on power consumption and performance (positiv or negativ) heavily

-frequency boost modes and their dependencies between other thread siblings
-and processor cores.

-
-Adjust the kernel's multi-core scheduler support.
