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
