Merge tag 'imx-drm-fixes-2015-12-01' of git://git.pengutronix.de/git/pza/linux into drm-fixes

imx-drm crtc, plane, parallel panel, and TV encoder fixes

- Use drm_crtc_send_vblank_event to fix per crtc vblank handling
- Move the crtc device of_node assignment out of the ipuv3-crtc driver into
  ipu-common code, where the devices are created.
- Fix parallel display support with simple-panels
- Remove some unused fields and superfluous checks
- Switch to universal planes and add error handling for primary plane creation
- Fix module autoload for TV encoder driver

  drm: imx: imx-tve: Fix module autoload for OF platform driver
  drm: imx: convert to drm_crtc_send_vblank_event()
  GPU-DRM-IMX: Delete an unnecessary check before drm_fbdev_cma_restore_mode()
  drm/imx: Remove of_node assignment from ipuv3-crtc driver probe
  gpu: ipu-v3: Assign of_node of child platform devices to corresponding ports
  gpu: ipu-v3: Remove reg_offset field
  gpu: ipu-v3: drop unused dmfc field from client platform data
  drm/imx: parallel-display: allow to determine bus format from the connected panel
  drm/imx: ipuv3-crtc: Return error if ipu_plane_init() fails for primary plane
  drm/imx: switch to universal planes
