This series enable CRTC color-mgmt for komeda driver, for current komeda HW which only supports color conversion and forward gamma for CRTC.
This series actually are regrouped from: - drm/komeda: Enable layer/plane color-mgmt: https://patchwork.freedesktop.org/series/60893/
- drm/komeda: Enable CRTC color-mgmt https://patchwork.freedesktop.org/series/61370/
For removing the dependence on: - https://patchwork.freedesktop.org/series/30876/
Lowry Li (Arm Technology China) (1): drm/komeda: Adds gamma and color-transform support for DOU-IPS
james qian wang (Arm Technology China) (3): drm/komeda: Add a new helper drm_color_ctm_s31_32_to_qm_n() drm/komeda: Add drm_lut_to_fgamma_coeffs() drm/komeda: Add drm_ctm_to_coeffs()
v2: Move the fixpoint conversion function s31_32_to_q2_12() to drm core as a shared helper.
