[PATCH RFC v4 7/7] drm/msm/dpu: Use DRM solid_fill property

Jessica Zhang
2023-06-30T00:26:22Z

Drop DPU_PLANE_COLOR_FILL_FLAG and check the DRM solid_fill property to
determine if the plane is solid fill. In addition drop the DPU plane
color_fill field as we can now use drm_plane_state.solid_fill instead,
and pass in drm_plane_state.alpha to _dpu_plane_color_fill_pipe() to
allow userspace to configure the alpha value for the solid fill color.
