This series adds support for the gamma and CTM properties to VC4.
I've sent the necessary register defs as part of the series this
time around to give the full picture.

The CTM support is somewhat limited in that we can only enable it for one
CRTC at a time and coefficients are S0.9 in hardware. The latter seems
good enough for the various color corrections Android offers.

Eric Anholt (1):
  drm/vc4: Add some missing HVS register definitions.

Stefan Schake (3):
  drm/vc4: Expose gamma as atomic property
  drm/vc4: Add color transformation matrix (CTM) support
  drm/vc4: Restrict active CTM to one CRTC
