Merge tag 'imx-drm-next-2016-11-10' of git://git.pengutronix.de/git/pza/linux into drm-next

imx-drm plane update cleanup, YUV formats

- request modeset if plane offsets changed, only the plane base
  address can be changed without disabling the plane IDMAC channel.
- cleanup of plane atomic_update
- remove unused ipu_cpmem_set_yuv_planar function
- support YUV 4:4:4, 4:2:2, NV12 and NV16 plane formats
- not only mask interrupts during irq init, also clear them
- remove a legacy check from imx-ldb
- add support to set the CSI downsizing bits
- silence an obnoxious warning during modeset
