The v11 can be found from: https://lore.kernel.org/all/20220301161156.1119557-1-tomi.valkeinen@ideasonboard.com/ My work branch with additional drivers can be found from: git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git streams/work-v12 And there's also the v4l-utils series v2 to add support to v4l2-ctl and media-ctl: https://lore.kernel.org/all/20220714132116.132498-1-tomi.valkeinen@ideasonboard.com/ Changes in v12: - Rebased on top of upstream (media graph walk changes, subdev active state changes) - V4L2_SUBDEV_FL_MULTIPLEXED renamed to V4L2_SUBDEV_FL_STREAMS - V4L2_SUBDEV_CAP_MPLEXED renamed to V4L2_SUBDEV_CAP_STREAMS - Limit Stream ID number to max 63 - Added v4l2_subdev_state_get_stream_crop() and v4l2_subdev_state_get_stream_compose() - Use BIT_ULL() instead of BIT() for 64bit masks. - Some documentation improvements - All the patches related to modifying the graph walk have been dropped and there is a new implementation of the pipeline construction in __media_pipeline_start. - The change which made media_pipeline_start() take a pad instead of an entity has been dropped. - New pipeline start/stop functions, media_pipeline_alloc_start() & media_pipeline_stop_free() There are still open discussion items wrt. the uAPI. I will post a mail in reply to this cover letter about those items.
