[PATCH RESEND v3 0/9] Add gamma lut support for mt8195

[Jason-JH.Lin]

Since the gamma_set_common() function for previous SoC,
such as  mt8173 and mt8183, is designed for 9bit-to-10bit
conversion.
mt8195 is using 10bit-to-12bit conversion, which is
not compatible with the previous function.

Thus, need to update the function to fit the need of mt8195.

Change in RESEND v3:
Fix build warning
>> drivers/gpu/drm/mediatek/mtk_disp_gamma.c:59:14: warning: no previous prototype for 'mtk_gamma_get_size' [-Wmissing-prototypes]

Change in v3:
1. separate 1 dt-binding patch to 2 patches, 1 is for modifying
   multiple items list to one and 1 is for moving mt8195 compatible.
2. redefine variables to reduce memory usage.
3. delete unused symbols.
4. separate 1 drm/mediatek patch to 6 patches.
5. rebase on tag 'next-20220909'

  drm/mediatek: Adjust mtk_drm_gamma_set_common parameters
  drm/mediatek: Add gamma support different lut_size for other SoC
  drm/mediatek: Add gamma support different lut_bits for other SoC
  drm/mediatek: Add gamma support different bank_size for other SoC
  drm/mediatek: Add clear RELAY_MODE bit to set gamma

zheng-yan.chen (4):
  dt-bindings: mediatek: modify item formatting for gamma
  dt-bindings: mediatek: Add gamma compatible for mt8195
  drm/mediatek: Add gamma lut support for mt8195
  arm64: dts: Modify gamma compatible for mt8195
