/**
 * DOC: The i915 register macro definition style guide
 *
 * Follow the style described here for new macros, and while changing existing
 * macros. Do **not** mass change existing definitions just to update the style.
 *
 * File Layout
 * ~~~~~~~~~~~
 *
 * Keep helper macros near the top. For example, _PIPE() and friends.
 *
 * Prefix macros that generally should not be used outside of this file with
 * underscore '_'. For example, _PIPE() and friends, single instances of
 * registers that are defined solely for the use by function-like macros.
 *
 * Avoid using the underscore prefixed macros outside of this file. There are
 * exceptions, but keep them to a minimum.
 *
 * There are two basic types of register definitions: Single registers and
 * register groups. Register groups are registers which have two or more
 * instances, for example one per pipe, port, transcoder, etc. Register groups
 * should be defined using function-like macros.
 *
 * For single registers, define the register offset first, followed by register
 * contents.
 *
 * For register groups, define the register instance offsets first, prefixed
 * with underscore, followed by a function-like macro choosing the right
 * instance based on the parameter, followed by register contents.
 *
 * Define the register contents (i.e. bit and bit field macros) from most
 * significant to least significant bit. Indent the register content macros
 * using two extra spaces between ``#define`` and the macro name.
 *
 * Define bit fields using ``REG_GENMASK(h, l)``. Define bit field contents
 * using ``REG_FIELD_PREP(mask, value)``. This will define the values already
 * shifted in place, so they can be directly OR'd together. For convenience,
 * function-like macros may be used to define bit fields, but do note that the
 * macros may be needed to read as well as write the register contents.
 *
 * Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.
 *
 * Group the register and its contents together without blank lines, separate
 * from other registers and their contents with one blank line.
 *
 * Indent macro values from macro names using TABs. Align values vertically. Use
 * braces in macro values as needed to avoid unintended precedence after macro
 * substitution. Use spaces in macro values according to kernel coding
 * style. Use lower case in hexadecimal values.
 *
 * Naming
 * ~~~~~~
 *
 * Try to name registers according to the specs. If the register name changes in
 * the specs from platform to another, stick to the original name.
 *
 * Try to re-use existing register macro definitions. Only add new macros for
 * new register offsets, or when the register contents have changed enough to
 * warrant a full redefinition.
 *
 * When a register macro changes for a new platform, prefix the new macro using
 * the platform acronym or generation. For example, ``SKL_`` or ``GEN8_``. The
 * prefix signifies the start platform/generation using the register.
 *
 * When a bit (field) macro changes or gets added for a new platform, while
 * retaining the existing register macro, add a platform acronym or generation
 * suffix to the name. For example, ``_SKL`` or ``_GEN8``.
 *
 * Examples
 * ~~~~~~~~
 *
 * (Note that the values in the example are indented using spaces instead of
 * TABs to avoid misalignment in generated documentation. Use TABs in the
 * definitions.)::
 *
 *  #define _FOO_A                      0xf000
 *  #define _FOO_B                      0xf001
 *  #define FOO(pipe)                   _MMIO_PIPE(pipe, _FOO_A, _FOO_B)

 *  #define   FOO_MODE_QUX_SNB          REG_FIELD_PREP(FOO_MODE_MASK, 2)
