Drop DPU_PLANE_COLOR_FILL_FLAG and check the DRM solid_fill property to

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.

As I commented for v4 (please excuse me for not responding to your
email at thattime), we can return abgr here, taking
plane->state->alpha into account.
Hi Dmitry,
Since it seems that this comment wasn't resolved, I can drop your R-B
tag in the next revision.
It's a minor issue, so no need to drop the tag.
From my previous response, I pointed out that the color parameter
expects an RGB value [1].
So is the intention here to refactor _dpu_plane_color_fill() to accept
an ABGR8888 color?
That's what I'm suggesting.
Thanks,
Jessica Zhang
