[PATCH v2 0/3] Add GAMMA 12-bit LUT support for MT8188

[PATCH v2 0/3] Add GAMMA 12-bit LUT support for MT8188

[Jason-JH.Lin]

From: Jason-jh Lin <jason-jh.lin@mediatek.corp-partner.google.com>

Since MT8195 supports GAMMA 12-bit LUT after the landing of [1] series,
we can now add support for MT8188.

[1] MediaTek DDP GAMMA - 12-bit LUT support
- https://patchwork.kernel.org/project/linux-mediatek/list/?series=792516

Change in v2:
1. Keep MT8195 compatible in the group of MT8183.
2. Move MT8195 compatible group to the end of items list.

  dt-bindings: display: mediatek: gamma: Change MT8195 to single enum
    group
  dt-bindings: display: mediatek: gamma: Add support for MT8188
  drm/mediatek: Add gamma support for MT8195

[PATCH v2 1/3] dt-bindings: display: mediatek: gamma: Change MT8195 to single enum group

[Jason-JH.Lin]

Since MT8195 gamma has multiple bank for 12 bits LUT and it is
different from any other SoC LUT setting.

So we add MT8195 compatible to the single enum group to make its
driver data settings can be reused by other SoC.

[PATCH v2 2/3] dt-bindings: display: mediatek: gamma: Add support for MT8188

[Jason-JH.Lin]

The gamma LUT setting of MT8188 and MT8195 are the same, so we create
a one of items for MT8188 to reuse the driver data settings of MT8195.

[PATCH v2 3/3] drm/mediatek: Add gamma support for MT8195

[Jason-JH.Lin]

Since MT8195 compatible is in the single enum group, we have to add its
compatible into mediatek-drm component binding table to ensure that
it can be bound as a ddp_comp.
