[RFC PATCH] drm: Add per-plane pixel blend mode property

2018-05-09 Thread Lowry Li
Pixel blend modes represent the alpha blending equation selection, describing how the pixels from the current plane are composited with the background. Add a pixel_blend_mode to drm_plane_state and a blend_mode_property to drm_plane, and related support functions. Defines three blend modes in
