Hi,
this series uses the IPU IC post-processing task to implement a mem2mem device for scaling and colorspace conversion. This version addresses a few review commends, and includes some further cleanup.
Changes since v2: - Limit downscaling to 4:1 - Disabled USERPTR memory - Set icc pointer to NULL on error - Dropped currently unused IDMAC channels - Fixed scaler module description - Embedded struct video_device
If it is acceptable, I'd like to merge this through drm-next via imx-drm. Mauro reportedly would be ok with that, and currently the potential for conflicts is limited to drivers/media/{Kconfig,Makefile}. If not, I'll postpone the two [media] patches for a release.
regards Philipp
