Subject: [PATCH v6 0/4] drm/komeda: Enable CRTC color-mgmt

Hi:

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.

v4:
  Address review comments from Mihai, Daniel and Ilia.

V5:
- Includes the sign bit in the value of m (Qm.n).
- Rebase with drm-misc-next

v6:
  Allows m == 0 according to Mihail's comments.
