Add support for solid_fill property to drm_plane. In addition, add support for setting and getting the values for solid_fill. solid_fill holds data for supporting solid fill planes. The property accepts an RGB323232 value and the driver data is formatted as such: struct drm_solid_fill { u32 r; u32 g; u32 b; }; To enable solid fill planes, userspace must assigned solid_fill to a property blob containing the following information: struct drm_solid_fill_info { u8 version; u32 r, g, b;
BTW: should we add support for alpha too? DPU hardware supports using RGBA as a fill colour format, doesn't it?
But then we face the obvious question, how do we communicate to userspace if the hardware support RGB or RGBA?
