+ * The functions here are used by the atomic plane helper functions to
+ * implement legacy plane updates (i.e., drm_plane->update_plane() and
+ * drm_plane->disable_plane()).  This allows plane updates to use the
+ * atomic state infrastructure and perform plane updates as separate
+ * prepare/check/commit/cleanup steps.
