Hi Tomi,
Thank you for the patch.

We currently have drm_atomic_helper_legacy_gamma_set() helper which can
be used to handle legacy gamma-set ioctl.
drm_atomic_helper_legacy_gamma_set() sets GAMMA_LUT, and clears
CTM and DEGAMMA_LUT. This works fine on HW where we have either:
degamma -> ctm -> gamma -> out
or
ctm -> gamma -> out
