This is MT8173 gamma & dither support PATCH v2, based on 4.7-rc1.

Changes since v1:
 -According to the suggestion from Daniel,
  we used the new atomic color management.
 -Applied gamma function at GAMMA engine (path 2).
 -Made dithering function support hardware mirroring well.
 -Removed the bpc variable from mtk_drm_crtc struct.
