[PATCH 0/6] drm/i915: introduce platform enum

[Jani Nikula]

The platform enum patch + some sugar coating on top.

BR,
Jani.

Jani Nikula (6):
  drm/i915: replace platform flags with a platform enum
  drm/i915: keep intel device info structs in gen based order
  drm/i915: rename BROADWATER and CRESTLINE to I965G and I965GM,
    respectively
  drm/i915: add some more "i" in platform names for consistency
  drm/i915: give G45 and GM45 their own platform enums
  drm/i915: use platform enum instead of duplicating PCI ID if possible

[PATCH 1/6] drm/i915: replace platform flags with a platform enum

[Jani Nikula]

The platform flags in device info are (mostly) mutually
exclusive. Replace the flags with an enum. Add the platform enum also
for platforms that previously didn't have a flag, and give them codename
logging in dmesg.

Pineview remains an exception, the platform being G33 for that.

v2: Sort enum by gen and date

The enum can be made into BIT() and the table can still be made with
some __builtin_ffs if that was found desireable.

With or without that;

[PATCH v3] drm/i915: replace platform flags with a platform enum

[Jani Nikula]

The platform flags in device info are (mostly) mutually
exclusive. Replace the flags with an enum. Add the platform enum also
for platforms that previously didn't have a flag, and give them codename
logging in dmesg.

Pineview remains an exception, the platform being G33 for that.

v2: Sort enum by gen and date

v3: rebase on geminilake enabling

Pushed this one, thanks for the review - which I failed to add to the
commit itself. /o\ Apologies!

Dare I still ask for review on patch 2/6...?

[PATCH 2/6] drm/i915: keep intel device info structs in gen based order

[Jani Nikula]

Move G33 and Pineview higher up in the list. Add a couple of blank lines
for OCD while at it.

[PATCH 3/6] drm/i915: rename BROADWATER and CRESTLINE to I965G and I965GM, respectively

[Jani Nikula]

Add more consistency to our naming. Pineview remains the outlier. Keep
using code names for gen5+.

[PATCH v2] drm/i915: rename BROADWATER and CRESTLINE to I965G and I965GM, respectively

[Jani Nikula]

Add more consistency to our naming. Pineview remains the outlier. Keep
using code names for gen5+.

v2: rebased
