- * this func is identical to the drm_atomic_helper_check, but we keep this
- * because we might eventually need to have a more finegrained check
- * sequence without using the atomic helpers.
- *
- * In the past, we first called drm_atomic_helper_check_planes, and then
- * drm_atomic_helper_check_modeset. We needed this because the MDP5 plane's
- * ->atomic_check could update ->mode_changed for pixel format changes.
- * This, however isn't needed now because if there is a pixel format change,
- * we just assign a new hwpipe for it with a new SMP allocation. We might
- * eventually hit a condition where we would need to do a full modeset if
- * we run out of planes. There, we'd probably need to set mode_changed.
