Some SoCs do 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 v9: 1. Add the fix patch for the XRGB8888 downgrade issue of MT8173 2. Add the refine patch for ignore_pixel_alpha statement Change in v8: Remove blend_modes for not supported pre-multiplied SoCs to fix the return error from drm_plane_create_blend_mode_property(). 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 (5): drm/mediatek: ovl: Fix XRGB format breakage for blend_modes unsupported SoCs drm/mediatek: ovl: Refine ignore_pixel_alpha comment and placement 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 drivers/gpu/drm/mediatek/mtk_crtc.c | 1 + drivers/gpu/drm/mediatek/mtk_ddp_comp.c | 2 + drivers/gpu/drm/mediatek/mtk_ddp_comp.h | 10 +++ drivers/gpu/drm/mediatek/mtk_disp_drv.h | 2 + drivers/gpu/drm/mediatek/mtk_disp_ovl.c | 70 ++++++++++++++----- .../gpu/drm/mediatek/mtk_disp_ovl_adaptor.c | 7 ++ drivers/gpu/drm/mediatek/mtk_ethdr.c | 7 ++ drivers/gpu/drm/mediatek/mtk_ethdr.h | 1 + drivers/gpu/drm/mediatek/mtk_plane.c | 15 ++-- drivers/gpu/drm/mediatek/mtk_plane.h | 4 +- 10 files changed, 92 insertions(+), 27 deletions(-) -- 2.43.0
