12   For compatability with legacy crtc helpers this should be called after
13   <code class="function">drm_atomic_helper_commit_planes</code>, which is what the default commit function
14   does. But drivers with different needs can group the modeset commits together
15   and do the plane commits at the end. This is useful for drivers doing runtime
16   PM since planes updates then only happen when the CRTC is actually enabled.
