Instead of using vblank to trigger psr enable/disable, use the flush
timer built for fb_dirty all of the time. This allows us to mitiage
the various edge cases, e.g. cursor. non-event updates, etc..

Sean Paul (3):
  drm/rockchip: Remove unnecessary vblank get/put from vop driver
  drm/rockchip: Don't key off vblank for psr
  drm/rockchip: Reduce psr flush time to 100ms
