drm/exynos: wait all planes updates to finish
Add infrastructure to wait for all planes updates to finish by using an atomic_t variable to track how many pending updates we are waiting plus a wait_queue for the wait part. It also changes vblank behaviour and keeps it enabled for all types of updates Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
