Merge branch 'for-next' of git://people.freedesktop.org/~seanpaul/dogwood into drm-next

This pull request contains the following rockchip drm changes:

  - Introduce support for rk3399 vop/crtc
  - Add PSR framework to the rockchip driver
  - Implement PSR in the rockchip analogix edp driver
  - Fix panel on/off in analogix to avoid damaging panels
  - Some miscellaneous fixes to clean up logs and code readability

* 'for-next' of git://people.freedesktop.org/~seanpaul/dogwood:
  drm/rockchip: analogix_dp: drop unnecessary probe deferral "error" print
  drm/rockchip: Enable vblank without event
  drm/rockchip: Improve analogix-dp psr handling
  drm/rockchip: A couple small fixes to psr
  drm/rockchip: Use a spinlock to protect psr state
  drm/rockchip: Don't use a delayed worker for psr state changes
  drm/rockchip: Convert psr_list_mutex to spinlock and use it
  drm/rockchip: analogix_dp: implement PSR function
  drm/bridge: analogix_dp: add the PSR function support
  drm/rockchip: add an common abstracted PSR driver
  drm/rockchip: vop: export line flag function
  drm/bridge: analogix_dp: Ensure the panel is properly prepared/unprepared
  dt-bindings: add compatible strings for big/little rockchip vops
  dt-bindings: sort Rockchip vop compatible by chip's number
  drm/rockchip: vop: add rk3399 vop support
  drm/rockchip: vop: introduce VOP_REG_MASK
  drm/rockchip: sort registers define by chip's number
