This adds a support for DRM_MODE_BLEND_PREMULTI. As a consequence, DRM_MODE_BLEND_PREMULTI becomes the default. If DRM_MODE_BLEND_COVERAGE is desired, it should be set explicitly. This behavior comes from how DRM blend mode is supported. drm_plane_create_blend_mode_property() creates the blend mode property with the default value of DRM_MODE_BLEND_PREMULTI. This default value cannot be modified from the atomic driver.
