[RFC PATCH 4/5] drm/drm_color_mgmt: add 3D LUT to color mgmt properties

2022-06-19 Thread Melissa Wen
Add 3D LUT for gammar correction using a 3D lookup table. The position in the color correction pipeline where 3D LUT is applied depends on hw design, being after CTM or gamma. If just after CTM, a shaper lut must be set to shape the content for a non-linear space. That details should be handled
