[v5,03/22] drm: Add color correction blobs in CRTC state

Commit Message

Sharma, Shashank Oct. 13, 2015, 12:39 p.m. UTC

This patch adds new variables in CRTC state, to hold respective color
correction blobs. These blobs will be required during the atomic commit
for writing the color correction values in correction registers.
