Unnecessary also? because be called by exynos_plane_atomic_update
already.

Should this go to .atomic_begin? Then you are missing drm_vblank_get
from a patch "drm/exynos: atomic phase 3: convert page flips"?

This .prepare and .prepare of encoder_helper_funcs are not used by
drm_atomic_helper_set_config so you can remove them from "drm/exynos:
atomic phase 3: use atomic .set_config helper"?

Could you make a split patch to move exynos_drm_crtc_disable function?
If not, we are difficult to understand code changes via diff.
Thanks.
