Merge tag 'drm-fixes-for-v4.9-rc6' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes fr9om Dave Airlie:
 "Fixes for amdgpu, and a bunch of arm drivers.

  There seems to be an uptick in the ARM drivers sending things for
  fixes which is good, so I've decided to dequeue a bit early, more
  stuff may arrive before the weekend.

  This contains mediatek, arcpgu, sunxi, fsl-dcu display controller
  fixes along with 3 amdgpu fixes, one for a fencing issue with
  secondary GPUs"

* tag 'drm-fixes-for-v4.9-rc6' of git://people.freedesktop.org/~airlied/linux:
  drm/amdgpu:fix vpost_needed routine
  drm/amdgpu/powerplay: drop a redundant NULL check
  drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5)
  drm/arcpgu: Accommodate adv7511 switch to DRM bridge
  drm/fsl-dcu: disable planes before disabling CRTC
  drm/fsl-dcu: update all registers on flush
  drm/fsl-dcu: do not update when modifying irq registers
  drm/sun4i: Propagate error to the caller
  drm/sun4i: Fix error handling
  drm/mediatek: modify the factor to make the pll_rate set in the 1G-2G range
  drm/mediatek: enhance the HDMI driving current
  drm/mediatek: do mtk_hdmi_send_infoframe after HDMI clock enable
  drm/mediatek: clear IRQ status before enable OVL interrupt
  drm/mediatek: set vblank_disable_allowed to true
  drm/mediatek: fix a typo of OD_CFG to OD_RELAYMODE
  drm/sun4i: rgb: Remove the bridge enable/disable functions
  drm/sun4i: rgb: Enable panel after controller
