+
+		To configure the timeout, write to this file a value along

+		Also note that only some timeouts are supported and that
+		some systems might fall back to a specific timeout in case
+		an invalid timeout is written to this file.

+		Chapter 20: Conditional Compilation
+
+Wherever possible, don't use preprocessor conditionals (#if, #ifdef) in .c
+files; doing so makes code harder to read and logic harder to follow.  Instead,
+use such conditionals in a header file defining functions for use in those .c
+files, providing no-op stub versions in the #else case, and then call those
+functions unconditionally from .c files.  The compiler will avoid generating
+any code for the stub calls, producing identical results, but the logic will
+remain easy to follow.
+
+Prefer to compile out entire functions, rather than portions of functions or
+portions of expressions.  Rather than putting an ifdef in an expression, factor
+out part or all of the expression into a separate helper function and apply the
+conditional to that function.
+
+If you have a function or variable which may potentially go unused in a
+particular configuration, and the compiler would warn about its definition
+going unused, mark the definition as __maybe_unused rather than wrapping it in
+a preprocessor conditional.  (However, if a function or variable *always* goes
+unused, delete it.)
+
+Within code, where possible, use the IS_ENABLED macro to convert a Kconfig
+symbol into a C boolean expression, and use it in a normal C conditional:
+
+	if (IS_ENABLED(CONFIG_SOMETHING)) {
+		...
+	}
+
+The compiler will constant-fold the conditional away, and include or exclude
+the block of code just as with an #ifdef, so this will not add any runtime
+overhead.  However, this approach still allows the C compiler to see the code
+inside the block, and check it for correctness (syntax, types, symbol
+references, etc).  Thus, you still have to use an #ifdef if the code inside the
+block references symbols that will not exist if the condition is not met.
+
+At the end of any non-trivial #if or #ifdef block (more than a few lines),
+place a comment after the #endif on the same line, noting the conditional
+expression used.  For instance:
+
+#ifdef CONFIG_SOMETHING
+...
+#endif /* CONFIG_SOMETHING */

+
+   <sect1><title>Introduction</title>
+
+    <para>
+     The kernel crypto API offers a rich set of cryptographic ciphers as
+     well as other data transformation mechanisms and methods to invoke
+     these. This document contains a description of the API and provides
+     example code.
+    </para>
+
+    <para>
+     To understand and properly use the kernel crypto API a brief
+     explanation of its structure is given. Based on the architecture,
+     the API can be separated into different components. Following the
+     architecture specification, hints to developers of ciphers are
+     provided. Pointers to the API function call  documentation are
+     given at the end.
+    </para>
+
+    <para>
+     The kernel crypto API refers to all algorithms as "transformations".
+     Therefore, a cipher handle variable usually has the name "tfm".
+     Besides cryptographic operations, the kernel crypto API also knows
+     compression transformations and handles them the same way as ciphers.
+    </para>
+
+    <para>
+     The kernel crypto API serves the following entity types:
+
+     <itemizedlist>

+       <para>consumers requesting cryptographic services</para>

+       that can be called by consumers using the kernel crypto

+    </para>
+
+    <para>
+     This specification is intended for consumers of the kernel crypto
+     API as well as for developers implementing ciphers. This API
+     specification, however, does not discusses all API calls available
+     to data transformation implementations (i.e. implementations of
+     ciphers and other transformations (such as CRC or even compression
+     algorithms) that can register with the kernel crypto API).
+    </para>
+
+    <para>
+     Note: The terms "transformation" and cipher algorithm are used
+     interchangably.

+
+   <sect1><title>Terminology</title>
+    <para>
+     The transformation implementation is an actual code or interface
+     to hardware which implements a certain transformation with precisely
+     defined behavior.
+    </para>
+
+    <para>
+     The transformation object (TFM) is an instance of a transformation
+     implementation. There can be multiple transformation objects
+     associated with a single transformation implementation. Each of
+     those transformation objects is held by a crypto API consumer or
+     another transformation. Transformation object is allocated when a
+     crypto API consumer requests a transformation implementation.
+     The consumer is then provided with a structure, which contains
+     a transformation object (TFM).
+    </para>
+
+    <para>
+     The structure that contains transformation objects may also be
+     referred to as a "cipher handle". Such a cipher handle is always
+     subject to the following phases that are reflected in the API calls
+     applicable to such a cipher handle:

+      <para>Destruction of a cipher handle.</para>
+     </listitem>
+    </orderedlist>
+
+    <para>
+     When using the initialization API calls, a cipher handle is
+     created and returned to the consumer. Therefore, please refer
+     to all initialization API calls that refer to the data
+     structure type a consumer is expected to receive and subsequently
+     to use. The initialization API calls have all the same naming
+     conventions of crypto_alloc_*.

+
+   <sect1><title>Ciphers And Templates</title>
+    <para>
+     The kernel crypto API provides implementations of single block
+     ciphers and message digests. In addition, the kernel crypto API
+     provides numerous "templates" that can be used in conjunction
+     with the single block ciphers and message digests. Templates
+     include all types of block chaining mode, the HMAC mechanism, etc.
+    </para>
+
+    <para>
+     Single block ciphers and message digests can either be directly
+     used by a caller or invoked together with a template to form
+     multi-block ciphers or keyed message digests.
+    </para>
+
+    <para>
+     A single block cipher may even be called with multiple templates.
+     However, templates cannot be used without a single cipher.
+    </para>
+
+    <para>
+     See /proc/crypto and search for "name". For example:
+
+     <itemizedlist>
+      <listitem><para>aes</para></listitem>

+     </itemizedlist>
+    </para>
+
+    <para>
+     In these examples, "aes" and "sha1" are the ciphers and all
+     others are the templates.
+    </para>
+   </sect1>
+
+   <sect1><title>Synchronous And Asynchronous Operation</title>
+    <para>
+     The kernel crypto API provides synchronous and asynchronous
+     API operations.
+    </para>
+
+    <para>
+     When using the synchronous API operation, the caller invokes
+     a cipher operation which is performed synchronously by the
+     kernel crypto API. That means, the caller waits until the
+     cipher operation completes. Therefore, the kernel crypto API
+     calls work like regular function calls. For synchronous
+     operation, the set of API calls is small and conceptually
+     similar to any other crypto library.
+    </para>
+
+    <para>
+     Asynchronous operation is provided by the kernel crypto API
+     which implies that the invocation of a cipher operation will
+     complete almost instantly. That invocation triggers the
+     cipher operation but it does not signal its completion. Before
+     invoking a cipher operation, the caller must provide a callback
+     function the kernel crypto API can invoke to signal the
+     completion of the cipher operation. Furthermore, the caller
+     must ensure it can handle such asynchronous events by applying
+     appropriate locking around its data. The kernel crypto API
+     does not perform any special serialization operation to protect
+     the caller's data integrity.
+    </para>
+   </sect1>
+
+   <sect1><title>Crypto API Cipher References And Priority</title>
+    <para>
+     A cipher is referenced by the caller with a string. That string
+     has the following semantics:
+
+     <programlisting>
+	template(single block cipher)
+     </programlisting>
+
+     where "template" and "single block cipher" is the aforementioned
+     template and single block cipher, respectively. If applicable,
+     additional templates may enclose other templates, such as
+
+      <programlisting>
+	template1(template2(single block cipher)))
+      </programlisting>
+    </para>
+
+    <para>
+     The kernel crypto API may provide multiple implementations of a
+     template or a single block cipher. For example, AES on newer
+     Intel hardware has the following implementations: AES-NI,
+     assembler implementation, or straight C. Now, when using the
+     string "aes" with the kernel crypto API, which cipher
+     implementation is used? The answer to that question is the
+     priority number assigned to each cipher implementation by the
+     kernel crypto API. When a caller uses the string to refer to a
+     cipher during initialization of a cipher handle, the kernel
+     crypto API looks up all implementations providing an
+     implementation with that name and selects the implementation
+     with the highest priority.
+    </para>
+
+    <para>
+     Now, a caller may have the need to refer to a specific cipher
+     implementation and thus does not want to rely on the
+     priority-based selection. To accommodate this scenario, the
+     kernel crypto API allows the cipher implementation to register
+     a unique name in addition to common names. When using that
+     unique name, a caller is therefore always sure to refer to
+     the intended cipher implementation.
+    </para>
+
+    <para>
+     The list of available ciphers is given in /proc/crypto. However,
+     that list does not specify all possible permutations of
+     templates and ciphers. Each block listed in /proc/crypto may
+     contain the following information -- if one of the components
+     listed as follows are not applicable to a cipher, it is not
+     displayed:

+
+   <sect1><title>Key Sizes</title>
+    <para>
+     When allocating a cipher handle, the caller only specifies the
+     cipher type. Symmetric ciphers, however, typically support
+     multiple key sizes (e.g. AES-128 vs. AES-192 vs. AES-256).
+     These key sizes are determined with the length of the provided
+     key. Thus, the kernel crypto API does not provide a separate
+     way to select the particular symmetric cipher key size.
+    </para>
+   </sect1>
+
+   <sect1><title>Cipher Allocation Type And Masks</title>
+    <para>
+     The different cipher handle allocation functions allow the
+     specification of a type and mask flag. Both parameters have
+     the following meaning (and are therefore not covered in the
+     subsequent sections).
+    </para>
+
+    <para>
+     The type flag specifies the type of the cipher algorithm.
+     The caller usually provides a 0 when the caller wants the
+     default handling. Otherwise, the caller may provide the
+     following selections which match the the aforementioned
+     cipher types:

+     The mask flag restricts the type of cipher. The only allowed

+     to asynchronous ciphers. Usually, a caller provides a 0 for the
+     mask flag.
+    </para>
+
+    <para>
+     When the caller provides a mask and type specification, the
+     caller limits the search the kernel crypto API can perform for
+     a suitable cipher implementation for the given cipher name.
+     That means, even when a caller uses a cipher name that exists
+     during its initialization call, the kernel crypto API may not
+     select it due to the used type and mask field.

+   <sect1><title>Registering And Unregistering Transformation</title>
+    <para>
+     There are three distinct types of registration functions in
+     the Crypto API. One is used to register a generic cryptographic
+     transformation, while the other two are specific to HASH
+     transformations and COMPRESSion. We will discuss the latter
+     two in a separate chapter, here we will only look at the
+     generic ones.
+    </para>
+
+    <para>
+     Before discussing the register functions, the data structure
+     to be filled with each, struct crypto_alg, must be considered
+     -- see below for a description of this data structure.
+    </para>
+
+    <para>
+     The generic registration functions can be found in
+     include/linux/crypto.h and their definition can be seen below.
+     The former function registers a single transformation, while
+     the latter works on an array of transformation descriptions.
+     The latter is useful when registering transformations in bulk.
+    </para>
+
+    <programlisting>
+   int crypto_register_alg(struct crypto_alg *alg);
+   int crypto_register_algs(struct crypto_alg *algs, int count);

+     The counterparts to those functions are listed below.

+   int crypto_unregister_algs(struct crypto_alg *algs, int count);
+    </programlisting>
+
+    <para>
+     Notice that both registration and unregistration functions
+     do return a value, so make sure to handle errors. A return
+     code of zero implies success. Any return code &lt; 0 implies
+     an error.
+    </para>
+
+    <para>
+     The bulk registration / unregistration functions require
+     that struct crypto_alg is an array of count size. These
+     functions simply loop over that array and register /
+     unregister each individual algorithm. If an error occurs,
+     the loop is terminated at the offending algorithm definition.
+     That means, the algorithms prior to the offending algorithm
+     are successfully registered. Note, the caller has no way of
+     knowing which cipher implementations have successfully
+     registered. If this is important to know, the caller should
+     loop through the different implementations using the single
+     instance *_alg functions for each individual implementation.

+    </para>
+
+    <para>
+     This section describes the multi-block cipher transformation
+     implementations for both synchronous [BLKCIPHER] and
+     asynchronous [ABLKCIPHER] case. The multi-block ciphers are
+     used for transformations which operate on scatterlists of
+     data supplied to the transformation functions. They output
+     the result into a scatterlist of data as well.

+
+    <sect2><title>Registration Specifics</title>
+
+     <para>
+      The registration of [BLKCIPHER] or [ABLKCIPHER] algorithms
+      is one of the most standard procedures throughout the crypto API.
+     </para>
+
+     <para>
+      Note, if a cipher implementation requires a proper alignment
+      of data, the caller should use the functions of
+      crypto_blkcipher_alignmask() or crypto_ablkcipher_alignmask()
+      respectively to identify a memory alignment mask. The kernel
+      crypto API is able to process requests that are unaligned.
+      This implies, however, additional overhead as the kernel
+      crypto API needs to perform the realignment of the data which
+      may imply moving of data.

+   <para>A monitor or TV will reproduce colors by emitting light at three

+technologies or uses. To define a colorspace you need to define the three
+color primaries (these are typically defined as x,&nbsp;y chromaticity coordinates
+from the CIE xyY colorspace) but also the white reference: that is the color obtained
+when all three primaries are at maximum power. This determines the relative power
+or energy of the primaries. This is usually chosen to be close to daylight which has
+been defined as the CIE D65 Illuminant.</para>

+    <para>Both the CIE XYZ and the RGB colorspace that are derived from the
+specific chromaticity primaries are linear colorspaces. But neither the eye,
+nor display technology is linear. Doubling the values of all components in
+the linear colorspace will not be perceived as twice the intensity of the color.
+So each colorspace also defines a transfer function that takes a linear color
+component value and transforms it to the non-linear component value, which is a
+closer match to the non-linear performance of both the eye and displays. Linear
+component values are denoted RGB, non-linear are denoted as R'G'B'. In general
+colors used in graphics are all R'G'B', except in openGL which uses linear RGB.
+Special care should be taken when dealing with openGL to provide linear RGB colors
+or to use the built-in openGL support to apply the inverse transfer function.</para>
 
-/* or shorter */
+    <para>The final piece that defines a colorspace is a function that
+transforms non-linear R'G'B' to non-linear Y'CbCr. This function is determined
+by the so-called luma coefficients. There may be multiple possible Y'CbCr
+encodings allowed for the same colorspace. Many encodings of color
+prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the human
+eye is more sensitive to differences in luminance than in color this encoding
+allows one to reduce the amount of color information compared to the luma
+data. Note that the luma (Y') is unrelated to the Y in the CIE XYZ colorspace.
+Also note that Y'CbCr is often called YCbCr or YUV even though these are
+strictly speaking wrong.</para>
 
-y1 = 0.299 * ER + 0.587 * EG + 0.114 * EB;
+    <para>Sometimes people confuse Y'CbCr as being a colorspace. This is not
+correct, it is just an encoding of an R'G'B' color into luma and chroma
+values. The underlying colorspace that is associated with the R'G'B' color
+is also associated with the Y'CbCr color.</para>

-      </programlisting>
+    <para>The final step is how the RGB, R'G'B' or Y'CbCr values are
+quantized. The CIE XYZ colorspace where X, Y and Z are in the range
+[0&hellip;1] describes all colors that humans can perceive, but the transform to
+another colorspace will produce colors that are outside the [0&hellip;1] range.
+Once clamped to the [0&hellip;1] range those colors can no longer be reproduced
+in that colorspace. This clamping is what reduces the extent or gamut of the
+colorspace. How the range of [0&hellip;1] is translated to integer values in the
+range of [0&hellip;255] (or higher, depending on the color depth) is called the
+quantization. This is <emphasis>not</emphasis> part of the colorspace
+definition. In practice RGB or R'G'B' values are full range, i.e. they
+use the full [0&hellip;255] range. Y'CbCr values on the other hand are limited

+standard only defines some, and you have to rely on other standards for

+The SMBus Driver (SSIF)
+-----------------------
+
+The SMBus driver allows up to 4 SMBus devices to be configured in the
+system.  By default, the driver will only register with something it
+finds in DMI or ACPI tables.  You can change this
+at module load time (for a module) with:
+
+  modprobe ipmi_ssif.o
+	addr=<i2caddr1>[,<i2caddr2>[,...]]
+	adapter=<adapter1>[,<adapter2>[...]]
+	dbg=<flags1>,<flags2>...
+        slave_addrs=<addr1>,<addr2>,...
+	[dbg_probe=1]
+
+The addresses are normal I2C addresses.  The adapter is the string
+name of the adapter, as shown in /sys/class/i2c-adapter/i2c-<n>/name.
+It is *NOT* i2c-<n> itself.
+
+The debug flags are bit flags for each BMC found, they are:
+IPMI messages: 1, driver state: 2, timing: 4, I2C probe: 8
+
+Setting dbg_probe to 1 will enable debugging of the probing and
+detection process for BMCs on the SMBusses.
+
+The slave_addrs specifies the IPMI address of the local BMC.  This is
+usually 0x20 and the driver defaults to that, but in case it's not, it
+can be specified when the driver starts up.
+
+Discovering the IPMI compliant BMC on the SMBus can cause devices on
+the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI
+message as a block write to the I2C bus and waits for a response.
+This action can be detrimental to some I2C devices. It is highly
+recommended that the known I2C address be given to the SMBus driver in
+the smb_addr parameter unless you have DMI or ACPI data to tell the
+driver what to use.
+
+When compiled into the kernel, the addresses can be specified on the
+kernel command line as:
+
+  ipmb_ssif.addr=<i2caddr1>[,<i2caddr2>[...]]
+	ipmi_ssif.adapter=<adapter1>[,<adapter2>[...]]
+	ipmi_ssif.dbg=<flags1>[,<flags2>[...]]
+	ipmi_ssif.dbg_probe=1
+        ipmi_ssif.slave_addrs=<addr1>[,<addr2>[...]]
+
+These are the same options as on the module command line.
+
+The I2C driver does not support non-blocking access or polling, so
+this driver cannod to IPMI panic events, extend the watchdog at panic
+time, or other panic-related IPMI functions without special kernel
+patches and driver modifications.  You can get those at the openipmi
+web page.
+
+The driver supports a hot add and remove of interfaces through the I2C
+sysfs interface.

 that the driver using the simple domain call irq_create_mapping()
 before any irq_find_mapping() since the latter will actually work
 for the static IRQ assignment case.
+
+==== Hierarchy IRQ domain ====
+On some architectures, there may be multiple interrupt controllers
+involved in delivering an interrupt from the device to the target CPU.
+Let's look at a typical interrupt delivering path on x86 platforms:
+
+Device --> IOAPIC -> Interrupt remapping Controller -> Local APIC -> CPU
+
+There are three interrupt controllers involved:
+1) IOAPIC controller
+2) Interrupt remapping controller
+3) Local APIC controller
+
+To support such a hardware topology and make software architecture match
+hardware architecture, an irq_domain data structure is built for each
+interrupt controller and those irq_domains are organized into hierarchy.
+When building irq_domain hierarchy, the irq_domain near to the device is
+child and the irq_domain near to CPU is parent. So a hierarchy structure
+as below will be built for the example above.
+	CPU Vector irq_domain (root irq_domain to manage CPU vectors)
+		^
+		|
+	Interrupt Remapping irq_domain (manage irq_remapping entries)
+		^
+		|
+	IOAPIC irq_domain (manage IOAPIC delivery entries/pins)
+
+There are four major interfaces to use hierarchy irq_domain:
+1) irq_domain_alloc_irqs(): allocate IRQ descriptors and interrupt
+   controller related resources to deliver these interrupts.
+2) irq_domain_free_irqs(): free IRQ descriptors and interrupt controller
+   related resources associated with these interrupts.
+3) irq_domain_activate_irq(): activate interrupt controller hardware to
+   deliver the interrupt.
+3) irq_domain_deactivate_irq(): deactivate interrupt controller hardware
+   to stop delivering the interrupt.
+
+Following changes are needed to support hierarchy irq_domain.
+1) a new field 'parent' is added to struct irq_domain; it's used to
+   maintain irq_domain hierarchy information.
+2) a new field 'parent_data' is added to struct irq_data; it's used to
+   build hierarchy irq_data to match hierarchy irq_domains. The irq_data
+   is used to store irq_domain pointer and hardware irq number.
+3) new callbacks are added to struct irq_domain_ops to support hierarchy
+   irq_domain operations.
+
+With support of hierarchy irq_domain and hierarchy irq_data ready, an
+irq_domain structure is built for each interrupt controller, and an
+irq_data structure is allocated for each irq_domain associated with an
+IRQ. Now we could go one step further to support stacked(hierarchy)
+irq_chip. That is, an irq_chip is associated with each irq_data along
+the hierarchy. A child irq_chip may implement a required action by
+itself or by cooperating with its parent irq_chip.
+
+With stacked irq_chip, interrupt controller driver only needs to deal
+with the hardware managed by itself and may ask for services from its
+parent irq_chip when needed. So we could achieve a much cleaner
+software architecture.
+
+For an interrupt controller driver to support hierarchy irq_domain, it
+needs to:
+1) Implement irq_domain_ops.alloc and irq_domain_ops.free
+2) Optionally implement irq_domain_ops.activate and
+   irq_domain_ops.deactivate.
+3) Optionally implement an irq_chip to manage the interrupt controller
+   hardware.
+4) No need to implement irq_domain_ops.map and irq_domain_ops.unmap,
+   they are unused with hierarchy irq_domain.
+
+Hierarchy irq_domain may also be used to support other architectures,
+such as ARM, ARM64 etc.

+_DSD Device Properties Related to GPIO
+--------------------------------------
+
+With the release of ACPI 5.1 and the _DSD configuration objecte names
+can finally be given to GPIOs (and other things as well) returned by
+_CRS.  Previously, we were only able to use an integer index to find
+the corresponding GPIO, which is pretty error prone (it depends on
+the _CRS output ordering, for example).
+
+With _DSD we can now query GPIOs using a name instead of an integer
+index, like the ASL example below shows:
+
+  // Bluetooth device with reset and shutdown GPIOs
+  Device (BTH)
+  {
+      Name (_HID, ...)
+
+      Name (_CRS, ResourceTemplate ()
+      {
+          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
+                  "\\_SB.GPO0", 0, ResourceConsumer) {15}
+          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
+                  "\\_SB.GPO0", 0, ResourceConsumer) {27, 31}
+      })
+
+      Name (_DSD, Package ()
+      {
+          ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+          Package ()
+	  {
+              Package () {"reset-gpio", Package() {^BTH, 1, 1, 0 }},
+              Package () {"shutdown-gpio", Package() {^BTH, 0, 0, 0 }},
+          }
+      })
+  }
+
+The format of the supported GPIO property is:
+
+  Package () { "name", Package () { ref, index, pin, active_low }}
+
+  ref - The device that has _CRS containing GpioIo()/GpioInt() resources,
+        typically this is the device itself (BTH in our case).
+  index - Index of the GpioIo()/GpioInt() resource in _CRS starting from zero.
+  pin - Pin in the GpioIo()/GpioInt() resource. Typically this is zero.
+  active_low - If 1 the GPIO is marked as active_low.
+
+Since ACPI GpioIo() resource does not have a field saying whether it is
+active low or high, the "active_low" argument can be used here.  Setting
+it to 1 marks the GPIO as active low.
+
+In our Bluetooth example the "reset-gpio" refers to the second GpioIo()
+resource, second pin in that resource with the GPIO number of 31.
+
+ACPI GPIO Mappings Provided by Drivers
+--------------------------------------
+
+There are systems in which the ACPI tables do not contain _DSD but provide _CRS
+with GpioIo()/GpioInt() resources and device drivers still need to work with
+them.
+
+In those cases ACPI device identification objects, _HID, _CID, _CLS, _SUB, _HRV,
+available to the driver can be used to identify the device and that is supposed
+to be sufficient to determine the meaning and purpose of all of the GPIO lines
+listed by the GpioIo()/GpioInt() resources returned by _CRS.  In other words,
+the driver is supposed to know what to use the GpioIo()/GpioInt() resources for
+once it has identified the device.  Having done that, it can simply assign names
+to the GPIO lines it is going to use and provide the GPIO subsystem with a
+mapping between those names and the ACPI GPIO resources corresponding to them.
+
+To do that, the driver needs to define a mapping table as a NULL-terminated
+array of struct acpi_gpio_mapping objects that each contain a name, a pointer
+to an array of line data (struct acpi_gpio_params) objects and the size of that
+array.  Each struct acpi_gpio_params object consists of three fields,
+crs_entry_index, line_index, active_low, representing the index of the target
+GpioIo()/GpioInt() resource in _CRS starting from zero, the index of the target
+line in that resource starting from zero, and the active-low flag for that line,
+respectively, in analogy with the _DSD GPIO property format specified above.
+
+For the example Bluetooth device discussed previously the data structures in
+question would look like this:
+
+static const struct acpi_gpio_params reset_gpio = { 1, 1, false };
+static const struct acpi_gpio_params shutdown_gpio = { 0, 0, false };
+
+static const struct acpi_gpio_mapping bluetooth_acpi_gpios[] = {
+  { "reset-gpio", &reset_gpio, 1 },
+  { "shutdown-gpio", &shutdown_gpio, 1 },
+  { },
+};
+
+Next, the mapping table needs to be passed as the second argument to
+acpi_dev_add_driver_gpios() that will register it with the ACPI device object
+pointed to by its first argument.  That should be done in the driver's .probe()
+routine.  On removal, the driver should unregister its GPIO mapping table by
+calling acpi_dev_remove_driver_gpios() on the ACPI device object where that
+table was previously registered.

+The arm64 port of the Linux kernel provides infrastructure to support
+emulation of instructions which have been deprecated, or obsoleted in
+the architecture. The infrastructure code uses undefined instruction
+hooks to support emulation. Where available it also allows turning on
+the instruction execution in hardware.
+
+The emulation mode can be controlled by writing to sysctl nodes

+behaviours and the corresponding values of the sysctl nodes -
+
+* Undef
+  Value: 0
+  Generates undefined instruction abort. Default for instructions that
+  have been obsoleted in the architecture, e.g., SWP
+
+* Emulate
+  Value: 1
+  Uses software emulation. To aid migration of software, in this mode
+  usage of emulated instruction is traced as well as rate limited
+  warnings are issued. This is the default for deprecated
+  instructions, .e.g., CP15 barriers
+
+* Hardware Execution
+  Value: 2
+  Although marked as deprecated, some implementations may support the
+  enabling/disabling of hardware support for the execution of these
+  instructions. Using hardware execution generally provides better
+  performance, but at the loss of ability to gather runtime statistics
+  about the use of the deprecated instructions.
+
+The default mode depends on the status of the instruction in the

+while obsolete instructions must be undefined by default.

- 	The usage value shows the amount of a resource that is consumed
-	by a group at a given time. The units of measurement should be
-	determined by the controller that uses this counter. E.g. it can
-	be bytes, items or any other unit the controller operates on.
-
- b. unsigned long long max_usage
-
- 	The maximal value of the usage over time.
-
- 	This value is useful when gathering statistical information about
-	the particular group, as it shows the actual resource requirements
-	for a particular group, not just some usage snapshot.
-
- c. unsigned long long limit
-
- 	The maximal allowed amount of resource to consume by the group. In
-	case the group requests for more resources, so that the usage value
-	would exceed the limit, the resource allocation is rejected (see
-	the next section).
-
- d. unsigned long long failcnt
-
- 	The failcnt stands for "failures counter". This is the number of
-	resource allocation attempts that failed.
-
- c. spinlock_t lock
-
- 	Protects changes of the above values.
-
-
-
-2. Basic accounting routines
-
- a. void res_counter_init(struct res_counter *rc,
-				struct res_counter *rc_parent)
-
- 	Initializes the resource counter. As usual, should be the first
-	routine called for a new counter.
-
-	The struct res_counter *parent can be used to define a hierarchical
-	child -> parent relationship directly in the res_counter structure,
-	NULL can be used to define no relationship.
-
- c. int res_counter_charge(struct res_counter *rc, unsigned long val,
-				struct res_counter **limit_fail_at)
-
-	When a resource is about to be allocated it has to be accounted
-	with the appropriate resource counter (controller should determine
-	which one to use on its own). This operation is called "charging".
-
-	This is not very important which operation - resource allocation
-	or charging - is performed first, but
-	  * if the allocation is performed first, this may create a
-	    temporary resource over-usage by the time resource counter is
-	    charged;
-	  * if the charging is performed first, then it should be uncharged
-	    on error path (if the one is called).
-
-	If the charging fails and a hierarchical dependency exists, the
-	limit_fail_at parameter is set to the particular res_counter element
-	where the charging failed.
-
- d. u64 res_counter_uncharge(struct res_counter *rc, unsigned long val)
-
-	When a resource is released (freed) it should be de-accounted
-	from the resource counter it was accounted to.  This is called
-	"uncharging". The return value of this function indicate the amount
-	of charges still present in the counter.
-
-	The _locked routines imply that the res_counter->lock is taken.
-
- e. u64 res_counter_uncharge_until
-		(struct res_counter *rc, struct res_counter *top,
-		 unsigned long val)
-
-	Almost same as res_counter_uncharge() but propagation of uncharge
-	stops when rc == top. This is useful when kill a res_counter in
-	child cgroup.
-
- 2.1 Other accounting routines
-
-    There are more routines that may help you with common needs, like
-    checking whether the limit is reached or resetting the max_usage
-    value. They are all declared in include/linux/res_counter.h.
-
-
-
-3. Analyzing the resource counter registrations
-
- a. If the failcnt value constantly grows, this means that the counter's
-    limit is too tight. Either the group is misbehaving and consumes too
-    many resources, or the configuration is not suitable for the group
-    and the limit should be increased.
-
- b. The max_usage value can be used to quickly tune the group. One may
-    set the limits to maximal values and either load the container with
-    a common pattern or leave one for a while. After this the max_usage
-    value shows the amount of memory the container would require during
-    its common activity.
-
-    Setting the limit a bit above this value gives a pretty good
-    configuration that works in most of the cases.
-
- c. If the max_usage is much less than the limit, but the failcnt value
-    is growing, then the group tries to allocate a big chunk of resource
-    at once.
-
- d. If the max_usage is much less than the limit, but the failcnt value
-    is 0, then this group is given too high limit, that it does not
-    require. It is better to lower the limit a bit leaving more resource
-    for other groups.
-
-
-
-4. Communication with the control groups subsystem (cgroups)
-
-All the resource controllers that are using cgroups and resource counters
-should provide files (in the cgroup filesystem) to work with the resource
-counter fields. They are recommended to adhere to the following rules:
-
- a. File names
-
- 	Field name	File name
-	---------------------------------------------------
-	usage		usage_in_<unit_of_measurement>
-	max_usage	max_usage_in_<unit_of_measurement>
-	limit		limit_in_<unit_of_measurement>
-	failcnt		failcnt
-	lock		no file :)
-
- b. Reading from file should show the corresponding field value in the
-    appropriate format.
-
- c. Writing to file
-
- 	Field		Expected behavior
-	----------------------------------
-	usage		prohibited
-	max_usage	reset to usage
-	limit		set the limit
-	failcnt		reset to zero
-
-
-
-5. Usage example
-
- a. Declare a task group (take a look at cgroups subsystem for this) and
-    fold a res_counter into it
-
-	struct my_group {
-		struct res_counter res;
-
-		<other fields>
-	}
-
- b. Put hooks in resource allocation/release paths
-
- 	int alloc_something(...)
-	{
-		if (res_counter_charge(res_counter_ptr, amount) < 0)
-			return -ENOMEM;
-
-		<allocate the resource and return to the caller>
-	}
-
-	void release_something(...)
-	{
-		res_counter_uncharge(res_counter_ptr, amount);
-
-		<release the resource>
-	}
-
-    In order to keep the usage value self-consistent, both the
-    "res_counter_ptr" and the "amount" in release_something() should be
-    the same as they were in the alloc_something() when the releasing
-    resource was allocated.
-
- c. Provide the way to read res_counter values and set them (the cgroups
-    still can help with it).
-
- c. Compile and run :)

+Introduction
+============
+
+The concepts of the kernel crypto API visible to kernel space is fully
+applicable to the user space interface as well. Therefore, the kernel crypto API
+high level discussion for the in-kernel use cases applies here as well.
+
+The major difference, however, is that user space can only act as a consumer
+and never as a provider of a transformation or cipher algorithm.
+
+The following covers the user space interface exported by the kernel crypto
+API. A working example of this description is libkcapi that can be obtained from
+[1]. That library can be used by user space applications that require
+cryptographic services from the kernel.
+
+Some details of the in-kernel kernel crypto API aspects do not
+apply to user space, however. This includes the difference between synchronous
+and asynchronous invocations. The user space API call is fully synchronous.
+In addition, only a subset of all cipher types are available as documented
+below.
+
+
+User space API general remarks
+==============================
+
+The kernel crypto API is accessible from user space. Currently, the following
+ciphers are accessible:
+
+	* Message digest including keyed message digest (HMAC, CMAC)
+
+	* Symmetric ciphers
+
+Note, AEAD ciphers are currently not supported via the symmetric cipher
+interface.
+
+The interface is provided via Netlink using the type AF_ALG. In addition, the
+setsockopt option type is SOL_ALG. In case the user space header files do not
+export these flags yet, use the following macros:
+
+#ifndef AF_ALG
+#define AF_ALG 38
+#endif
+#ifndef SOL_ALG
+#define SOL_ALG 279
+#endif
+
+A cipher is accessed with the same name as done for the in-kernel API calls.
+This includes the generic vs. unique naming schema for ciphers as well as the
+enforcement of priorities for generic names.
+
+To interact with the kernel crypto API, a Netlink socket must be created by
+the user space application. User space invokes the cipher operation with the
+send/write system call family. The result of the cipher operation is obtained
+with the read/recv system call family.
+
+The following API calls assume that the Netlink socket descriptor is already
+opened by the user space application and discusses only the kernel crypto API
+specific invocations.
+
+To initialize a Netlink interface, the following sequence has to be performed
+by the consumer:
+
+	1. Create a socket of type AF_ALG with the struct sockaddr_alg parameter
+	   specified below for the different cipher types.
+
+	2. Invoke bind with the socket descriptor
+
+	3. Invoke accept with the socket descriptor. The accept system call
+	   returns a new file descriptor that is to be used to interact with
+	   the particular cipher instance. When invoking send/write or recv/read
+	   system calls to send data to the kernel or obtain data from the
+	   kernel, the file descriptor returned by accept must be used.
+
+In-place cipher operation
+=========================
+
+Just like the in-kernel operation of the kernel crypto API, the user space
+interface allows the cipher operation in-place. That means that the input buffer
+used for the send/write system call and the output buffer used by the read/recv
+system call may be one and the same. This is of particular interest for
+symmetric cipher operations where a copying of the output data to its final
+destination can be avoided.
+
+If a consumer on the other hand wants to maintain the plaintext and the
+ciphertext in different memory locations, all a consumer needs to do is to
+provide different memory pointers for the encryption and decryption operation.
+
+Message digest API
+==================
+
+The message digest type to be used for the cipher operation is selected when
+invoking the bind syscall. bind requires the caller to provide a filled
+struct sockaddr data structure. This data structure must be filled as follows:
+
+struct sockaddr_alg sa = {
+	.salg_family = AF_ALG,
+	.salg_type = "hash", /* this selects the hash logic in the kernel */
+	.salg_name = "sha1" /* this is the cipher name */
+};
+
+The salg_type value "hash" applies to message digests and keyed message digests.
+Though, a keyed message digest is referenced by the appropriate salg_name.
+Please see below for the setsockopt interface that explains how the key can be
+set for a keyed message digest.
+
+Using the send() system call, the application provides the data that should be
+processed with the message digest. The send system call allows the following
+flags to be specified:
+
+	* MSG_MORE: If this flag is set, the send system call acts like a
+		    message digest update function where the final hash is not
+		    yet calculated. If the flag is not set, the send system call
+		    calculates the final message digest immediately.
+
+With the recv() system call, the application can read the message digest from
+the kernel crypto API. If the buffer is too small for the message digest, the
+flag MSG_TRUNC is set by the kernel.
+
+In order to set a message digest key, the calling application must use the
+setsockopt() option of ALG_SET_KEY. If the key is not set the HMAC operation is
+performed without the initial HMAC state change caused by the key.
+
+
+Symmetric cipher API
+====================
+
+The operation is very similar to the message digest discussion. During
+initialization, the struct sockaddr data structure must be filled as follows:
+
+struct sockaddr_alg sa = {
+	.salg_family = AF_ALG,
+	.salg_type = "skcipher", /* this selects the symmetric cipher */
+	.salg_name = "cbc(aes)" /* this is the cipher name */
+};
+
+Before data can be sent to the kernel using the write/send system call family,
+the consumer must set the key. The key setting is described with the setsockopt
+invocation below.
+
+Using the sendmsg() system call, the application provides the data that should
+be processed for encryption or decryption. In addition, the IV is specified
+with the data structure provided by the sendmsg() system call.
+
+The sendmsg system call parameter of struct msghdr is embedded into the
+struct cmsghdr data structure. See recv(2) and cmsg(3) for more information
+on how the cmsghdr data structure is used together with the send/recv system
+call family. That cmsghdr data structure holds the following information
+specified with a separate header instances:
+
+	* specification of the cipher operation type with one of these flags:
+		ALG_OP_ENCRYPT - encryption of data
+		ALG_OP_DECRYPT - decryption of data
+
+	* specification of the IV information marked with the flag ALG_SET_IV
+
+The send system call family allows the following flag to be specified:
+
+	* MSG_MORE: If this flag is set, the send system call acts like a
+		    cipher update function where more input data is expected
+		    with a subsequent invocation of the send system call.
+
+Note: The kernel reports -EINVAL for any unexpected data. The caller must
+make sure that all data matches the constraints given in /proc/crypto for the
+selected cipher.
+
+With the recv() system call, the application can read the result of the
+cipher operation from the kernel crypto API. The output buffer must be at least
+as large as to hold all blocks of the encrypted or decrypted data. If the output
+data size is smaller, only as many blocks are returned that fit into that
+output buffer size.
+
+Setsockopt interface
+====================
+
+In addition to the read/recv and send/write system call handling to send and
+retrieve data subject to the cipher operation, a consumer also needs to set
+the additional information for the cipher operation. This additional information
+is set using the setsockopt system call that must be invoked with the file
+descriptor of the open cipher (i.e. the file descriptor returned by the
+accept system call).
+
+Each setsockopt invocation must use the level SOL_ALG.
+
+The setsockopt interface allows setting the following data using the mentioned
+optname:
+
+	* ALG_SET_KEY -- Setting the key. Key setting is applicable to:
+
+		- the skcipher cipher type (symmetric ciphers)
+
+		- the hash cipher type (keyed message digests)
+
+User space API example
+======================
+
+Please see [1] for libkcapi which provides an easy-to-use wrapper around the
+aforementioned Netlink kernel interface. [1] also contains a test application
+that invokes all libkcapi API calls.

+* CoreSight Components:
+
+CoreSight components are compliant with the ARM CoreSight architecture
+specification and can be connected in various topologies to suit a particular
+SoCs tracing needs. These trace components can generally be classified as
+sinks, links and sources. Trace data produced by one or more sources flows
+through the intermediate links connecting the source to the currently selected
+sink. Each CoreSight component device should use these properties to describe
+its hardware characteristcs.
+
+* Required properties for all components *except* non-configurable replicators:
+
+	* compatible: These have to be supplemented with "arm,primecell" as
+	  drivers are using the AMBA bus interface.  Possible values include:
+		- "arm,coresight-etb10", "arm,primecell";
+		- "arm,coresight-tpiu", "arm,primecell";
+		- "arm,coresight-tmc", "arm,primecell";
+		- "arm,coresight-funnel", "arm,primecell";
+		- "arm,coresight-etm3x", "arm,primecell";
+
+	* reg: physical base address and length of the register
+	  set(s) of the component.
+
+	* clocks: the clock associated to this component.
+
+	* clock-names: the name of the clock as referenced by the code.
+	  Since we are using the AMBA framework, the name should be
+	  "apb_pclk".
+
+	* port or ports: The representation of the component's port
+	  layout using the generic DT graph presentation found in
+	  "bindings/graph.txt".
+
+* Required properties for devices that don't show up on the AMBA bus, such as
+  non-configurable replicators:
+
+	* compatible: Currently supported value is (note the absence of the
+	  AMBA markee):
+		- "arm,coresight-replicator"
+
+	* id: a unique number that will identify this replicator.
+
+	* port or ports: same as above.
+
+* Optional properties for ETM/PTMs:
+
+	* arm,cp14: must be present if the system accesses ETM/PTM management
+	  registers via co-processor 14.
+
+	* cpu: the cpu phandle this ETM/PTM is affined to. When omitted the
+	  source is considered to belong to CPU0.
+
+* Optional property for TMC:
+
+	* arm,buffer-size: size of contiguous buffer space for TMC ETR
+	 (embedded trace router)

+The chosen node
+---------------
+
+The chosen node does not represent a real device, but serves as a place
+for passing data between firmware and the operating system, like boot
+arguments. Data in the chosen node does not represent the hardware.
+
+
+stdout-path property
+--------------------
+
+Device trees may specify the device to be used for boot console output
+with a stdout-path property under /chosen, as described in ePAPR, e.g.
+
+/ {
+	chosen {
+		stdout-path = "/serial@f00:115200";
+	};
+
+	serial@f00 {
+		compatible = "vendor,some-uart";
+		reg = <0xf00 0x10>;
+	};
+};
+
+If the character ":" is present in the value, this terminates the path.
+The meaning of any characters following the ":" is device-specific, and
+must be specified in the relevant binding documentation.
+
+For UART devices, the preferred binding is a string in the form:
+
+	<baud>{<parity>{<bits>{<flow>}}}
+
+where
+
+	baud	- baud rate in decimal
+	parity	- 'n' (none), 'o', (odd) or 'e' (even)
+	bits	- number of data bits
+	flow	- 'r' (rts)
+
+For example: 115200n8r
+
+Implementation note: Linux will look for the property "linux,stdout-path" or
+on PowerPC "stdout" if "stdout-path" is not found.  However, the
+"linux,stdout-path" and "stdout" properties are deprecated. New platforms
+should only use the "stdout-path" property.

+* Freescale VF610 PORT/GPIO module
+
+The Freescale PORT/GPIO modules are two adjacent modules providing GPIO

+
+Required properties for GPIO node:
+- compatible : Should be "fsl,<soc>-gpio", currently "fsl,vf610-gpio"
+- reg : The first reg tuple represents the PORT module, the second tuple
+  the GPIO module.
+- interrupts : Should be the port interrupt shared by all 32 pins.
+- gpio-controller : Marks the device node as a gpio controller.
+- #gpio-cells : Should be two. The first cell is the pin number and

+      0 = active high
+      1 = active low
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells : Should be 2.  The first cell is the GPIO number.
+  The second cell bits[3:0] is used to specify trigger type and level flags:

+      2 = high-to-low edge triggered.
+      4 = active high level-sensitive.
+      8 = active low level-sensitive.

+Qualcomm's SPMI PMIC current ADC
+
+QPNP PMIC current ADC (IADC) provides interface to clients to read current.
+A 16 bit ADC is used for current measurements. IADC can measure the current
+through an external resistor (channel 1) or internal (built-in) resistor
+(channel 0). When using an external resistor it is to be described by
+qcom,external-resistor-micro-ohms property.
+
+IADC node:
+
+- compatible:
+    Usage: required
+    Value type: <string>
+    Definition: Should contain "qcom,spmi-iadc".
+
+- reg:
+    Usage: required
+    Value type: <prop-encoded-array>
+    Definition: IADC base address and length in the SPMI PMIC register map
+
+- interrupts:
+    Usage: optional
+    Value type: <prop-encoded-array>
+    Definition: End of ADC conversion.
+
+- qcom,external-resistor-micro-ohms:

+    Value type: <u32>
+    Definition: Sense resister value in micro Ohm.
+                If not defined value of 10000 micro Ohms will be used.

+Sharp Microelectronics 10.1" WQXGA TFT LCD panel
+
+This panel requires a dual-channel DSI host to operate. It supports two modes:
+- left-right: each channel drives the left or right half of the screen
+- even-odd: each channel drives the even or odd lines of the screen
+
+Each of the DSI channels controls a separate DSI peripheral. The peripheral
+driven by the first link (DSI-LINK1), left or even, is considered the primary
+peripheral and controls the device. The 'link2' property contains a phandle
+to the peripheral driven by the second link (DSI-LINK2, right or odd).
+
+Note that in video mode the DSI-LINK1 interface always provides the left/even
+pixels and DSI-LINK2 always provides the right/odd pixels. In command mode it
+is possible to program either link to drive the left/even or right/odd pixels
+but for the sake of consistency this binding assumes that the same assignment
+is chosen as for video mode.
+
+Required properties:
+- compatible: should be "sharp,lq101r1sx01"
+- reg: DSI virtual channel of the peripheral
+
+Required properties (for DSI-LINK1 only):
+- link2: phandle to the DSI peripheral on the secondary link. Note that the
+  presence of this property marks the containing node as DSI-LINK1.
+- power-supply: phandle of the regulator that provides the supply voltage
+
+Optional properties (for DSI-LINK1 only):
+- backlight: phandle of the backlight device attached to the panel
+

+STMicroelectronics STi MIPHY28LP PHY binding
+============================================
+
+This binding describes a miphy device that is used to control PHY hardware
+for SATA, PCIe or USB3.
+
+Required properties (controller (parent) node):
+- compatible	: Should be "st,miphy28lp-phy".
+- st,syscfg	: Should be a phandle of the system configuration register group
+		  which contain the SATA, PCIe or USB3 mode setting bits.
+
+Required nodes	:  A sub-node is required for each channel the controller
+		   provides. Address range information including the usual
+		   'reg' and 'reg-names' properties are used inside these
+		   nodes to describe the controller's topology. These nodes
+		   are translated by the driver's .xlate() function.
+
+Required properties (port (child) node):
+- #phy-cells	: Should be 1 (See second example)
+		  Cell after port phandle is device type from:
+			- PHY_TYPE_SATA
+			- PHY_TYPE_PCI
+			- PHY_TYPE_USB3
+- reg		: Address and length of the register set for the device.
+- reg-names	: The names of the register addresses corresponding to the registers
+		  filled in "reg". It can also contain the offset of the system configuration
+		  registers used as glue-logic to setup the device for SATA/PCIe or USB3
+		  devices.
+- resets	: phandle to the parent reset controller.
+- reset-names	: Associated name must be "miphy-sw-rst".
+
+Optional properties (port (child) node):
+- st,osc-rdy		: to check the MIPHY0_OSC_RDY status in the glue-logic. This
+			  is not available in all the MiPHY. For example, for STiH407, only the
+			  MiPHY0 has this bit.
+- st,osc-force-ext	: to select the external oscillator. This can change from
+			  different MiPHY inside the same SoC.
+- st,sata_gen		: to select which SATA_SPDMODE has to be set in the SATA system config
+			  register.
+- st,px_rx_pol_inv	: to invert polarity of RXn/RXp (respectively negative line and positive
+			  line).
+- st,scc-on		: enable ssc to reduce effects of EMI (only for sata or PCIe).
+- st,tx-impedance-comp	: to compensate tx impedance avoiding out of range values.
+
+example:
+
+		miphy28lp_phy: miphy28lp@9b22000 {

+
+
+Specifying phy control of devices
+=================================
+
+Device nodes should specify the configuration required in their "phys"
+property, containing a phandle to the miphy device node and an index
+specifying which configuration to use, as described in phy-bindings.txt.
+
+example:
+		sata0: sata@9b20000  {
+			...
+			phys		= <&phy_port0 PHY_TYPE_SATA>;
+			...
+		};

+ - "ao-bank" for the always-on domain
+
+=== Other sub-nodes ===
+
+Child nodes without the "gpio-controller" represent some desired
+configuration for a pin or a group. Those nodes can be pinmux nodes or
+configuration nodes.
+
+Required properties for pinmux nodes are:
+ - groups: a list of pinmux groups. The list of all available groups
+   depends on the SoC and can be found in driver sources.
+ - function: the name of a function to activate for the specified set
+   of groups. The list of all available functions depends on the SoC
+   and can be found in driver sources.
+
+Required properties for configuration nodes:
+ - pins: a list of pin names
+
+Configuration nodes support the generic properties "bias-disable",
+"bias-pull-up" and "bias-pull-down", described in file
+pinctrl-bindings.txt
+
+=== Example ===
+

+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin or a list of pins. This configuration can include the
+mux function to select on those pin(s), and various pin configuration

+
+
+SUBNODES:
+
+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:

 common pinctrl bindings used by client devices, including the meaning of the
 phrase "pin configuration node".
 
-ST Ericsson's pin configuration nodes act as a container for an arbitrary 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 input, output, pull up, pull down...
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Required subnode-properties:
-- ste,pins : An array of strings. Each string contains the name of a pin or
-    group.
-
-Optional subnode-properties:
-- ste,function: A string containing the name of the function to mux to the
-  pin or group.
-
-- generic pin configuration option to use. Example :
-
-	default_cfg {
-		ste,pins = "GPIO1";
-		bias-disable;
-	};
-
-- ste,config: Handle of pin configuration node containing the generic
-  pinconfig options to use, as described in pinctrl-bindings.txt in

+* Generic system power control capability
+
+Power-management integrated circuits or miscellaneous hardware components are
+sometimes able to control the system power. The device driver associated with these
+components might need to define this capability, which tells the kernel that
+it can be used to switch off the system. The corresponding device must have the
+standard property "system-power-controller" in its device node. This property
+marks the device as able to control the system power. In order to test if this
+property is found programmatically, use the helper function
+"of_device_is_system_power_controller" from of.h .
+
+Example:
+
+act8846: act8846@5 {
+	 compatible = "active-semi,act8846";
+	 status = "okay";
+	 system-power-controller;
+}

+The max77802 regulator supports two different operating modes: Normal and Low
+Power Mode. Some regulators support the modes to be changed at startup or by
+the consumers during normal operation while others only support to change the
+mode during system suspend. The standard regulator suspend states binding can

+
+The regulators that support the standard "regulator-initial-mode" property,
+changing their mode during normal operation are: LDOs 1, 3, 20 and 21.
+
+The possible values for "regulator-initial-mode" and "regulator-mode" are:
+	1: Normal regulator voltage output mode.
+	3: Low Power which reduces the quiescent current down to only 1uA
+
+The list of valid modes are defined in the dt-bindings/clock/maxim,max77802.h

+The standard "regulator-mode" property can only be used for regulators that
+support changing their mode to Low Power Mode during suspend. These regulators
+are: BUCKs 2-4 and LDOs 1-35. Also, it only takes effect if the regulator has
