/*
* 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.
