This is a follow-on set to Yakir's original PSR set here:
and applies to the for-next branch at:

There are a few issues with the code that needed to be
shored up.
 (1) The use of mutexes instead of spinlocks caused issues calling the
     psr functions from vblank_enable/disable.
 (2) The proliferation of workers due to (1)
 (3) A bunch of races due to (2)
 (4) vblank is not enabled unless an event is requested, this breaks
     a lot of things, but most noticeable was cursor.

Changes in v2:
	- Rebased on https://cgit.freedesktop.org/~seanpaul/dogwood
	  instead of random on-list patches (some of which had drifted)
	- Added the "small fixes" patch to catch some nits

Sean Paul (6):
  drm/rockchip: Convert psr_list_mutex to spinlock and use it
  drm/rockchip: Don't use a delayed worker for psr state changes
  drm/rockchip: Use a spinlock to protect psr state
  drm/rockchip: A couple small fixes to psr
  drm/rockchip: Improve analogix-dp psr handling
  drm/rockchip: Enable vblank without event
