32  * DOC: The i915 register macro definition style guide
33  *
34  * Follow the style described here for new macros, and while changing existing
35  * macros. Do **not** mass change existing definitions just to update the style.
36  *
37  * File Layout
38  * ~~~~~~~~~~~
39  *
40  * Keep helper macros near the top. For example, _PIPE() and friends.
41  *
42  * Prefix macros that generally should not be used outside of this file with
43  * underscore '_'. For example, _PIPE() and friends, single instances of
44  * registers that are defined solely for the use by function-like macros.
45  *
46  * Avoid using the underscore prefixed macros outside of this file. There are
47  * exceptions, but keep them to a minimum.
48  *
49  * There are two basic types of register definitions: Single registers and
50  * register groups. Register groups are registers which have two or more
51  * instances, for example one per pipe, port, transcoder, etc. Register groups
52  * should be defined using function-like macros.
53  *
54  * For single registers, define the register offset first, followed by register
55  * contents.
56  *
57  * For register groups, define the register instance offsets first, prefixed
58  * with underscore, followed by a function-like macro choosing the right
59  * instance based on the parameter, followed by register contents.
60  *
61  * Define the register contents (i.e. bit and bit field macros) from most
62  * significant to least significant bit. Indent the register content macros
63  * using two extra spaces between ``#define`` and the macro name.
64  *
65  * Define bit fields using ``REG_GENMASK(h, l)``. Define bit field contents
66  * using ``REG_FIELD_PREP(mask, value)``. This will define the values already
67  * shifted in place, so they can be directly OR'd together. For convenience,
68  * function-like macros may be used to define bit fields, but do note that the
69  * macros may be needed to read as well as write the register contents.
70  *
71  * Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.
72  *
73  * Group the register and its contents together without blank lines, separate
74  * from other registers and their contents with one blank line.
75  *
76  * Indent macro values from macro names using TABs. Align values vertically. Use
77  * braces in macro values as needed to avoid unintended precedence after macro
78  * substitution. Use spaces in macro values according to kernel coding
79  * style. Use lower case in hexadecimal values.
80  *
81  * Naming
82  * ~~~~~~
83  *
84  * Try to name registers according to the specs. If the register name changes in
85  * the specs from platform to another, stick to the original name.
86  *
87  * Try to reuse existing register macro definitions. Only add new macros for
88  * new register offsets, or when the register contents have changed enough to
89  * warrant a full redefinition.
90  *
91  * When a register macro changes for a new platform, prefix the new macro using
92  * the platform acronym or generation. For example, ``SKL_`` or ``GEN8_``. The
93  * prefix signifies the start platform/generation using the register.
94  *
95  * When a bit (field) macro changes or gets added for a new platform, while
96  * retaining the existing register macro, add a platform acronym or generation
97  * suffix to the name. For example, ``_SKL`` or ``_GEN8``.
98  *
99  * Examples
100  * ~~~~~~~~
101  *
102  * (Note that the values in the example are indented using spaces instead of
103  * TABs to avoid misalignment in generated documentation. Use TABs in the
104  * definitions.)::
