-BCM2835 PM (Power domains, watchdog)
-
-The PM block controls power domains and some reset lines, and includes
-a watchdog timer. This binding supersedes the brcm,bcm2835-pm-wdt
-binding which covered some of PM's register range and functionality.
-
-Required properties:
-
-- compatible: Should be "brcm,bcm2835-pm"
-- reg: Specifies base physical address and size of the two
- register ranges ("PM" and "ASYNC_BRIDGE" in that
- order)
-- clocks: a) v3d: The V3D clock from CPRMAN
- b) peri_image: The PERI_IMAGE clock from CPRMAN
- c) h264: The H264 clock from CPRMAN
- d) isp: The ISP clock from CPRMAN
-- #reset-cells: Should be 1. This property follows the reset controller
- bindings[1].
-- #power-domain-cells: Should be 1. This property follows the power domain
- bindings[2].
-
-Optional properties:
-
-- timeout-sec: Contains the watchdog timeout in seconds
-- system-power-controller: Whether the watchdog is controlling the
- system power. This node follows the power controller bindings[3].

+ * NOTE
+ * Unless indicated otherwise, don't use ';' after these macros as it
+ * messes up the kABI checker by changing what the resulting token string
+ * looks like. Instead let the macros add the ';' so it can be properly
+ * hidden from the kABI checker (mainly for RH_KABI_EXTEND, but applied to
+ * most macros for uniformity).
+ *
+ *
+ * RH_KABI_CONST
+ * Adds a new const modifier to a function parameter preserving the old
+ * checksum.
+ *
+ * RH_KABI_ADD_MODIFIER
+ * Adds a new modifier to a function parameter or a typedef, preserving
+ * the old checksum. Useful e.g. for adding rcu annotations or changing
+ * int to unsigned. Beware that this may change the semantics; if you're
+ * sure this is safe, always explain why binary compatibility with 3rd
+ * party modules is retained.
+ *
+ * RH_KABI_DEPRECATE
+ * Marks the element as deprecated and make it unusable by modules while
+ * keeping a hole in its place to preserve binary compatibility.
+ *
+ * RH_KABI_DEPRECATE_FN
+ * Marks the function pointer as deprecated and make it unusable by modules
+ * while keeping a hole in its place to preserve binary compatibility.
+ *
+ * RH_KABI_EXTEND
+ * Adds a new field to a struct. This must always be added to the end of
+ * the struct. Before using this macro, make sure this is actually safe
+ * to do - there is a number of conditions under which it is *not* safe.
+ * In particular (but not limited to), this macro cannot be used:
+ * - if the struct in question is embedded in another struct, or
+ * - if the struct is allocated by drivers either statically or
+ * dynamically, or
+ * - if the struct is allocated together with driver data (an example of
+ * such behavior is struct net_device or struct request).
+ *
+ * RH_KABI_EXTEND_WITH_SIZE
+ * Adds a new element (usually a struct) to a struct and reserves extra
+ * space for the new element. The provided 'size' is the total space to
+ * be added in longs (i.e. it's 8 * 'size' bytes), including the size of
+ * the added element. It is automatically checked that the new element
+ * does not overflow the reserved space, now nor in the future. However,
+ * no attempt is done to check the content of the added element (struct)
+ * for kABI conformance - kABI checking inside the added element is
+ * effectively switched off.
+ * For any struct being added by RH_KABI_EXTEND_WITH_SIZE, it is
+ * recommended its content to be documented as not covered by kABI
+ * guarantee.
+ *
+ * RH_KABI_FILL_HOLE
+ * Fills a hole in a struct.
+ *
+ * Warning: only use if a hole exists for _all_ arches. Use pahole to verify.
+ *
+ * RH_KABI_RENAME
+ * Renames an element without changing its type. This macro can be used in
+ * bitfields, for example.
+ *
+ * NOTE: this macro does not add the final ';'
+ *
+ * RH_KABI_REPLACE
+ * Replaces the _orig field by the _new field. The size of the occupied
+ * space is preserved, it's fine if the _new field is smaller than the
+ * _orig field. If a _new field is larger or has a different alignment,
+ * compilation will abort.
+ *
+ * RH_KABI_REPLACE_SPLIT
+ * Works the same as RH_KABI_REPLACE but replaces a single _orig field by
+ * multiple new fields. The checks for size and alignment done by
+ * RH_KABI_REPLACE are still applied.
+ *
+ * RH_KABI_HIDE_INCLUDE
+ * Hides the given include file from kABI checksum computations. This is
+ * used when a newly added #include makes a previously opaque struct
+ * visible.
+ *
+ * Example usage:
+ * #include RH_KABI_HIDE_INCLUDE(<linux/poll.h>)
+ *
+ * RH_KABI_FAKE_INCLUDE
+ * Pretends inclusion of the given file for kABI checksum computations.
+ * This is used when upstream removed a particular #include but that made
+ * some structures opaque that were previously visible and is causing kABI
+ * checker failures.
+ *
+ * Example usage:
+ * #include RH_KABI_FAKE_INCLUDE(<linux/rhashtable.h>)
+ *
+ * RH_KABI_RESERVE
+ * Adds a reserved field to a struct. This is done prior to kABI freeze
+ * for structs that cannot be expanded later using RH_KABI_EXTEND (for
+ * example because they are embedded in another struct or because they are
+ * allocated by drivers or because they use unusual memory layout). The
+ * size of the reserved field is 'unsigned long' and is assumed to be
+ * 8 bytes.
+ *
+ * The argument is a number unique for the given struct; usually, multiple
+ * RH_KABI_RESERVE macros are added to a struct with numbers starting from
+ * one.
+ *
+ * Example usage:
+ * struct foo {
+ * int a;
+ * RH_KABI_RESERVE(1)
+ * RH_KABI_RESERVE(2)
+ * RH_KABI_RESERVE(3)
+ * RH_KABI_RESERVE(4)
+ * };
+ *
+ * RH_KABI_USE
+ * Uses a previously reserved field or multiple fields. The arguments are
+ * one or more numbers assigned to RH_KABI_RESERVE, followed by a field to
+ * be put in their place. The compiler ensures that the new field is not
+ * larger than the reserved area.
+ *
+ * Example usage:
+ * struct foo {
+ * int a;
+ * RH_KABI_USE(1, int b)
+ * RH_KABI_USE(2, 3, int c[3])
+ * RH_KABI_RESERVE(4)
+ * };
+ *
+ * RH_KABI_USE_SPLIT
+ * Works the same as RH_KABI_USE but replaces a single reserved field by
+ * multiple new fields.
+ *
+ * RH_KABI_AUX_EMBED
+ * RH_KABI_AUX_PTR
+ * Adds an extenstion of a struct in the form of "auxiliary structure".
+ * This is done prior to kABI freeze for structs that cannot be expanded
+ * later using RH_KABI_EXTEND. See also RH_KABI_RESERVED, these two
+ * approaches can (and often are) combined.
+ *
+ * To use this for 'struct foo' (the "base structure"), define a new
+ * structure called 'struct foo_rh'; this new struct is called "auxiliary
+ * structure". Then add RH_KABI_AUX_EMBED or RH_KABI_AUX_PTR to the end
+ * of the base structure. The argument is the name of the base structure,
+ * without the 'struct' keyword.
+ *
+ * RH_KABI_AUX_PTR stores a pointer to the aux structure in the base
+ * struct. The lifecycle of the aux struct needs to be properly taken
+ * care of.
+ *
+ * RH_KABI_AUX_EMBED embeds the aux struct into the base struct. This
+ * cannot be used when the base struct is itself embedded into another
+ * struct, allocated in an array, etc.
+ *
+ * Both approaches (ptr and embed) work correctly even when the aux struct
+ * is allocated by modules. To ensure this, the code responsible for
+ * allocation/assignment of the aux struct has to properly set the size of
+ * the aux struct; see the RH_KABI_AUX_SET_SIZE and RH_KABI_AUX_INIT_SIZE
+ * macros.
+ *
+ * New fields can be later added to the auxiliary structure, always to its
+ * end. Note the auxiliary structure cannot be shrunk in size later (i.e.,
+ * fields cannot be removed, only deprecated). Any code accessing fields
+ * from the aux struct must guard the access using the RH_KABI_AUX macro.
+ * The access itself is then done via a '_rh' field in the base struct.
+ *
+ * The auxiliary structure is not guaranteed for access by modules unless
+ * explicitly commented as such in the declaration of the aux struct
+ * itself or some of its elements.
+ *
+ * Example:
+ *
+ * struct foo_rh {
+ * int newly_added;
+ * };
+ *
+ * struct foo {
+ * bool big_hammer;
+ * RH_KABI_AUX_PTR(foo)
+ * };
+ *
+ * void use(struct foo *f)
+ * {
+ * if (RH_KABI_AUX(f, foo, newly_added))
+ * f->_rh->newly_added = 123;
+ * else
+ * // the field 'newly_added' is not present in the passed
+ * // struct, fall back to old behavior
+ * f->big_hammer = true;
+ * }
+ *
+ * static struct foo_rh my_foo_rh {
+ * .newly_added = 0;
+ * }
+ *
+ * static struct foo my_foo = {
+ * .big_hammer = false,
+ * ._rh = &my_foo_rh,
+ * RH_KABI_AUX_INIT_SIZE(foo)
+ * };
+ *
+ * RH_KABI_USE_AUX_PTR
+ * Creates an auxiliary structure post kABI freeze. This works by using
+ * two reserved fields (thus there has to be two reserved fields still
+ * available) and converting them to RH_KABI_AUX_PTR.
+ *
+ * Example:
+ *
+ * struct foo_rh {
+ * };
+ *
+ * struct foo {
+ * int a;
+ * RH_KABI_RESERVE(1)
+ * RH_KABI_USE_AUX_PTR(2, 3, foo)
+ * };
+ *
+ * RH_KABI_AUX_SET_SIZE
+ * RH_KABI_AUX_INIT_SIZE
+ * Calculates and stores the size of the auxiliary structure.
+ *
+ * RH_KABI_AUX_SET_SIZE is for dynamically allocated base structs,
+ * RH_KABI_AUX_INIT_SIZE is for statically allocated case structs.
+ *
+ * These macros must be called from the allocation (RH_KABI_AUX_SET_SIZE)
+ * or declaration (RH_KABI_AUX_INIT_SIZE) site, regardless of whether
+ * that happens in the kernel or in a module. Without calling one of
+ * these macros, the aux struct will appear to have no fields to the
+ * kernel.
+ *
+ * Note: since RH_KABI_AUX_SET_SIZE is intended to be invoked outside of
+ * a struct definition, it does not add the semicolon and must be
+ * terminated by semicolon by the caller.
+ *
+ * RH_KABI_AUX
+ * Verifies that the given field exists in the given auxiliary structure.
+ * This MUST be called prior to accessing that field; failing to do that
+ * may lead to invalid memory access.
+ *
+ * The first argument is a pointer to the base struct, the second argument
+ * is the name of the base struct (without the 'struct' keyword), the
+ * third argument is the field name.
+ *
+ * This macro works for structs extended by either of RH_KABI_AUX_EMBED,
+ * RH_KABI_AUX_PTR and RH_KABI_USE_AUX_PTR.
+ *
+ * RH_KABI_FORCE_CHANGE
+ * Force change of the symbol checksum. The argument of the macro is a
+ * version for cases we need to do this more than once.
+ *
+ * This macro does the opposite: it changes the symbol checksum without
+ * actually changing anything about the exported symbol. It is useful for
+ * symbols that are not whitelisted, we're changing them in an
+ * incompatible way and want to prevent 3rd party modules to silently
+ * corrupt memory. Instead, by changing the symbol checksum, such modules
+ * won't be loaded by the kernel. This macro should only be used as a
+ * last resort when all other KABI workarounds have failed.
+ *
+ * RH_KABI_EXCLUDE
+ * !!! WARNING: DANGEROUS, DO NOT USE unless you are aware of all the !!!
+ * !!! implications. This should be used ONLY EXCEPTIONALLY and only !!!
+ * !!! under specific circumstances. Very likely, this macro does not !!!
+ * !!! do what you expect it to do. Note that any usage of this macro !!!
+ * !!! MUST be paired with a RH_KABI_FORCE_CHANGE annotation of !!!
+ * !!! a suitable symbol (or an equivalent safeguard) and the commit !!!
+ * !!! log MUST explain why the chosen solution is appropriate. !!!
+ *
+ * Exclude the element from checksum generation. Any such element is
+ * considered not to be part of the kABI whitelist and may be changed at
+ * will. Note however that it's the responsibility of the developer
+ * changing the element to ensure 3rd party drivers using this element
+ * won't panic, for example by not allowing them to be loaded. That can
+ * be achieved by changing another, non-whitelisted symbol they use,
+ * either by nature of the change or by using RH_KABI_FORCE_CHANGE.
+ *
+ * Also note that any change to the element must preserve its size. Change
+ * of the size is not allowed and would constitute a silent kABI breakage.
+ * Beware that the RH_KABI_EXCLUDE macro does not do any size checks.
+ *
+ * RH_KABI_BROKEN_INSERT
+ * RH_KABI_BROKEN_REMOVE
+ * Insert a field to the middle of a struct / delete a field from a struct.
+ * Note that this breaks kABI! It can be done only when it's certain that
+ * no 3rd party driver can validly reach into the struct. A typical
+ * example is a struct that is: both (a) referenced only through a long
+ * chain of pointers from another struct that is part of a whitelisted
+ * symbol and (b) kernel internal only, it should have never been visible
+ * to genksyms in the first place.
+ *
+ * Another example are structs that are explicitly exempt from kABI
+ * guarantee but we did not have enough foresight to use RH_KABI_EXCLUDE.
+ * In this case, the warning for RH_KABI_EXCLUDE applies.
+ *
+ * A detailed explanation of correctness of every RH_KABI_BROKEN_* macro
+ * use is especially important.
+ *
+ * RH_KABI_BROKEN_INSERT_BLOCK
+ * RH_KABI_BROKEN_REMOVE_BLOCK
+ * A version of RH_KABI_BROKEN_INSERT / REMOVE that allows multiple fields
+ * to be inserted or removed together. All fields need to be terminated
+ * by ';' inside(!) the macro parameter. The macro itself must not be
+ * terminated by ';'.
+ *
+ * RH_KABI_BROKEN_REPLACE
+ * Replace a field by a different one without doing any checking. This
+ * allows replacing a field by another with a different size. Similarly
+ * to other RH_KABI_BROKEN macros, use of this indicates a kABI breakage.
+ *
+ * RH_KABI_BROKEN_INSERT_ENUM
+ * RH_KABI_BROKEN_REMOVE_ENUM
+ * Insert a field to the middle of an enumaration type / delete a field from
+ * an enumaration type. Note that this can break kABI especially if the
+ * number of enum fields is used in an array within a structure. It can be
+ * done only when it is certain that no 3rd party driver will use the
+ * enumeration type or a structure that embeds an array with size determined
+ * by an enumeration type.
+ *
+ * RH_KABI_EXTEND_ENUM
+ * Adds a new field to an enumeration type. This must always be added to
+ * the end of the enum. Before using this macro, make sure this is actually
+ * safe to do.
