[Intel-gfx] [PATCH v2 0/4] drm/i915: introduce macros to define register contents

[Jani Nikula]

The v1 [1] kind of died down because the FIELD_PREP() build-time checks
were lost as it didn't evaluate to integer constant expression. I looked
at this again, and managed to include the checks in the local copy by
using BUILD_BUG_ON_ZERO() instead.

On the naming bikeshedding department, I noticed a clash with regmap.h
REG_FIELD() and, since it all looked pretty verbose anyway, decided to
see if local _BIT(), _MASK(), and _FIELD() would stick.

BR,
Jani.
