Subject: drm/msm: add dirty framebuffer helper
X-Git-Tag: v5.3-rc1~81^2~9^2

drm/msm: add dirty framebuffer helper

Use drm_atomic_helper_dirtyfb() as the dirty callback in the
msm_framebuffer_funcs struct. Call drm_plane_enable_fb_damage_clips()
when the planes are initialized in mdp4, mdp5, and dpu1.
