The series of patches adds support for DRM pixel blend mode to R-Car DU driver. The current R-Car DU implicitly supports "Coverage" only. Unfortunately, this changes the default blending mode of R-Car DU to "Pre-multiplied" which is the default when pixel blend mode is supported. v2: vsp1: - Add a premult flag instead of blend mode enum rcar-du: - Support DRM_MODE_BLEND_PREMULTI via the premult flag - Support DRM_MODE_BLEND_PIXEL_NONE via format override [1] [1] https://lore.kernel.org/linux-renesas-soc/20220704025231.3911138-1-taki@xxxxxxxxxx/T/#m3351cb5965cd5bf2d416fa5ca5007773260205bd Takanari Hayama (3): media: vsp1: add premultiplied alpha support drm: rcar-du: Add DRM_MODE_BLEND_PREMULTI support drm: rcar-du: Add DRM_MODE_BLEND_PIXEL_NONE support drivers/gpu/drm/rcar-du/rcar_du_vsp.c | 26 ++++++++++++++++++- .../media/platform/renesas/vsp1/vsp1_drm.c | 2 ++ include/media/vsp1.h | 2 ++ 3 files changed, 29 insertions(+), 1 deletion(-) -- 2.25.1
