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.
