/*

 * 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.
