[PATCH 0/3] drm/vc4: Atomic color management support

This series adds support for the gamma and CTM properties to VC4. Patches 2 and 3 need the register definitions from here:

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 still seem good enough for the various color corrections Android offers.

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
