From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>
Hi,
This patchset adds a couple of changes to improve atomic modesetting:
* add check for the START shadow register for FIMD to only finish the update
when the screen was actually updated.
* add asynchronous atomic commit, so now page flips can be run asynchronously.
It also add infrastructure to serialize commits for the same CRTC and wait all
plane updates to finish.
* enable the DRIVER_ATOMIC feature to enable userspace to use atomic IOCTL with
exynos.
v2: rename prepare_plane/cleanup_plane to atomic_begin/atomic_flush
Please review.
Gustavo
