Merge tag 'imx-drm-next-2018-07-20' of git://git.pengutronix.de/git/pza/linux into drm-next
drm/imx: cleanup and csi improvements
- Remove the unused struct imx_drm_crtc and the unused pipes field
from imx_drm_device and replace drm_dev_unref with drm_dev_put.
- Extend CSI configuration to support RGB888 and BGR888 capture,
as well as 16-bit RGB565 capture via a parallel bus.
- Add CPMEM support for negative interlace offsets, which is
necessary to support writing captured bottom-top interlaced
fields to memory with interleaved lines.
