Merge tag 'imx-drm-fixes-2018-08-03' of git://git.pengutronix.de/git/pza/linux into drm-next
drm/imx: ipu-v3 plane offset and IPU id fixes
- Fix U/V plane offsets for odd vertical offsets. Due to wrong operator
order, the y offset was not rounded down properly for vertically
chroma subsampled planar formats.
- Fix IPU id number for boards that don't have an OF alias for their
single IPU in the device tree. This is necessary to support imx-media
on i.MX51 and i.MX53 SoCs.
