Yes. > If so, the atomic_state is bypassed into > mtk_drm_crtc_atomic_eanble() and you could sync it here. > I'vd tried this method. It can also fix this problem. So I'll use atomic_state to update mtk_plane_state here.

OVL layer should not be enabled before crtc is enabled. The plane_state of drm_atomic_state is not sync to the plane_state stored in mtk_crtc during crtc enabling, so just set all planes to disabled.
