Subject: [PATCH 00/11] MediaTek DDP GAMMA - 12-bit LUT support

This series adds support for GAMMA IP requiring and/or supporting
a 12-bits LUT using a slightly different register layout and programming
sequence for multiple LUT banks: this IP version is currently found
on a number of SoCs, not only including the Chromebook/IoT oriented
Kompanio 1200/1380 MT8195/MT8195T, but also Smartphone chips such as
the Dimensity 9200 (MT6985) and others.

This series was tested on MT8195, MT8192, MT8173, MT6795:
 * MT6795, MT8192, MT8173: No regression, works fine.
 * MT8195: Color correction is finally working!

AngeloGioacchino Del Regno (10):
  drm/mediatek: gamma: Reduce indentation in mtk_gamma_set_common()
  drm/mediatek: gamma: Support SoC specific LUT size
  drm/mediatek: gamma: Improve and simplify HW LUT calculation
  drm/mediatek: gamma: Enable the Gamma LUT table only after programming
  drm/mediatek: gamma: Use bitfield macros
  drm/mediatek: gamma: Support specifying number of bits per LUT
    component
  drm/mediatek: gamma: Support multi-bank gamma LUT
  drm/mediatek: gamma: Add support for 12-bit LUT and MT8195
  drm/mediatek: gamma: Make sure relay mode is disabled
  drm/mediatek: gamma: Program gamma LUT type for descending or rising

Jason-JH.Lin (1):
  drm/mediatek: gamma: Adjust mtk_drm_gamma_set_common parameters
