Merge tag 'imx-drm-next-2019-07-05' of git://git.pengutronix.de/git/pza/linux into drm-next
drm/imx: IPUv3 image converter improvements, enable scanout FIFO watermark
- Fix a saturation bit position in the colorspace converter
configuration memory.
- Fully describe colorspace conversions in the API to the imx-media driver.
- Add support for limited range and Rec.709 YUV encoding.
- Enable colorimetry configuration via the media-controller API.
- Enable the double write reduction feature for memory bandwidth savings
when the image converter writes YUV 4:2:0 output.
- Enable a scanout FIFO watermark feature that can increase priority of
scanout read transfers at the memory controller whenever the FIFO runs
low.
