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. Please review.
