[GIT PULL] drm/imx: IPUv3 image converter improvements, enable scanout FIFO watermark

[Philipp Zabel]

Hi Dave, Daniel,

please consider merging these (mostly image converter) updates for v5.3.

This series changes the API between ipu-v3 and the imx-media driver to
enable improved colorimetry configuration of the image converter, and so
it contains commits that touch drivers/staging/media.

As a result, there is going to be a trivial merge conflict between
commit f208b26e61df ("gpu: ipu-v3: ipu-ic: Fully describe colorspace
conversions") in this series and commit 34ff38745b16 ("media:
staging/imx: Pass device to alloc/free_dma_buf") from
git://linuxtv.org/media_tree.git master, due to overlapping context.

regards
Philipp

  gpu: ipu-v3: image-convert: Enable double write reduction (2019-06-14 15:33:02 +0200)

----------------------------------------------------------------
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.
