From: Hsiao Chien Sung <shawn.sung@xxxxxxxxxxxx> Support "Pre-multiplied" alpha blending mode in Mixer. Before this patch, only the coverage mode is supported. To replace the default setting that is set in mtk_ethdr_config(), we change mtk_ddp_write_mask() to mtk_ddp_write(), and this change will also reset the NON_PREMULTI_SOURCE bit that was assigned in mtk_ethdr_config(). Therefore, we must still set NON_PREMULTI_SOURCE bit if the blend mode is not DRM_MODE_BLEND_PREMULTI. Signed-off-by: Hsiao Chien Sung <shawn.sung@xxxxxxxxxxxx>
