Hi Dave,
This tag contains a few cleanup patches, and adds support for setting a
bit in the channel parameter memory to stop the IPU from writing the
chroma lines twice for YUV420 and NV12 formats.
regards
Philipp

gpu: ipu-v3: vdic: include AUTO field order bit in ipu_vdi_set_field_order (2017-06-08 08:57:20 +0200)
----------------------------------------------------------------
imx-drm: cleanups and YUV 4:2:0 memory read/write reduction support
- Remove counter load enable form PRE, which has no effect.
- Add support for setting the double read/write reduction flag in channel
parameter memory. This can be used to save some memory bandwidth when
capturing in YUV 4:2:0 chroma subsampled formats.
- Allocate DMA channel structures as needed, most of the 64 channels are
unused or even reserved.
- Remove unused interrupt busy waiting routine.
- Set VDIC field order for both AUTO and MAN inputs simultaneously as
both can't be active at the same time.
