[Intel-gfx] [PATCH v3 00/20] drm/i915: Finish (de)gamma readout

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The gamma readout stuff was left half finished. No degamma
readout, and no readout whatsoever on ivb/bdw/skl/bxt.
Let's finish it.

Since we have the {pre,post}_csc_lut stuff this is fairly
easy to do now. The implementation of the LUT checker is
a bit more repetitive than I'd like but we an work on
shrinking it later.

There are some fixes/cleanups at the start, and while we're
in there let's also throw in the 10bit gamma mode for gen2/3.
At the end I also added a few patches to fix existing issues
with gamma vs. YCbCr/RGB limited range output.

v2: Mostly redone, only some of the readout implementations
    remain more or less unchange
v3: More work towards C8 palette readout, but disable the
    state checker for it now since we lack c8_planes readout
