Hi, This is v15 of the streams series. The v14 can be found from: https://lore.kernel.org/all/20220831141357.1396081-1-tomi.valkeinen@xxxxxxxxxxxxxxxx/ My work branch with additional drivers can be found from: git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git streams/work-v15 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@xxxxxxxxxxxxxxxx/ This series is based on top of linux-media-stage, and this series is now smaller as many patches from v14 have been merged. Changes in v15: media: v4l2-subdev: Sort includes - New patch media: add V4L2_SUBDEV_CAP_STREAMS - Small refactor to use 'streams_subdev' variable media: Documentation: Add GS_ROUTING documentation - Improve error code descriptions media: subdev: Add [GS]_ROUTING subdev ioctls and operations - Return E2BIG when there are too many routes in VIDIOC_SUBDEV_S_ROUTING - Use plain bitshift in the uapi header instead of _BITUL() - V4L2_SUBDEV_ROUTE_FL_SOURCE is now bit 1, so if you have userspace which uses V4L2_SUBDEV_ROUTE_FL_SOURCE, you need to recompile media: subdev: add v4l2_subdev_set_routing helper() - Check for overflow in v4l2_subdev_set_routing() media: subdev: add stream based configuration - Fix compilation for !CONFIG_VIDEO_V4L2_SUBDEV_API or !CONFIG_MEDIA_CONTROLLER media: subdev: use streams in v4l2_subdev_link_validate() - Modify link validation to use 64bit streams-mask instead of collecting stream IDs into allocated arrays. This simplifies the functions quite a bit.
