[PATCH v7 0/3] Fix degradation problem of alpha blending series

[Jason-JH.Lin]

Some SoCs not support pre-multiplied pixel formats and extending
configuration of OVL pre-multiplied color formats, such as MT8173.

Fix the SoC degradation problem by this sreies.

---

Change in v7:
1. Add the remove color format comment patch for OVL
2. Fix warning: 'const' type qualifier on return type has no effect

Chnage in v6:
1. Use blend_modes instead of function pointer in OVL
2. Use ethdr instead of mdp_rdma to get blend_modes
3. Add 0 checking for adding blend_mode property for mtk_plane

Change in v5:
Add fix patch for mtk_plane

Change in v4:
Add lost cases of mtk_ovl_fmt_convert_with_blend

Change in v3:
Change MACRO approach to function pointer in driver data

Change in v2:
Fix build error and typo

Change in v1:
Add fix patch for OVL unsupport color format settings by driver data

Jason-JH.Lin (3):
  drm/mediatek: ovl: Remove the color format comment for
    ovl_fmt_convert()
  drm/mediatek: ovl: Add blend_modes to driver data
  drm/mediatek: Add blend_modes to mtk_plane_init() for different SoCs
