Hi, This is v13 of the streams series. The v12 can be found from: https://lore.kernel.org/all/20220727103639.581567-1-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-v13 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/ Changes in v13 to v12 * media_pipeline_alloc_start: handle no mem error * Automatically free the allocated pipeline in media_pipeline_stop() * sanity checks for media_entity_pipeline * improve v4l2_link_validate_get_streams (drop 'is_source') * indent Add iterator helper for entity pads * v4l2_subdev_set_routing: leave the current routing untouched in case of error * v4l2_subdev_init_stream_configs: leave the current routing untouched in case of error * Drop V4L2_SUBDEV_ROUTE_FL_IMMUTABLE * In subdev ioctls, check that stream == 0 if subdev doesn't support streams * Squash for_each_active_route() uses * Add media_pad_pipeline() * Add video device pipeline helpers and use them in the drivers * Rename has_route to has_pad_interdep Tomi Jacopo Mondi (3): media: mc: entity: Add iterator helper for entity pads media: Documentation: Add GS_ROUTING documentation media: subdev: Add for_each_active_route() macro Laurent Pinchart (9): media: mc: entity: Merge media_entity_enum_init and __media_entity_enum_init media: mc: entity: Move media_entity_get_fwnode_pad() out of graph walk section media: mc: entity: Add media_entity_pipeline() to access the media pipeline media: mc: entity: Rewrite media_pipeline_start() media: subdev: Add [GS]_ROUTING subdev ioctls and operations media: subdev: add v4l2_subdev_routing_validate() helper media: v4l2-subdev: Add v4l2_subdev_state_xlate_streams() helper media: v4l2-subdev: Add subdev .(enable|disable)_streams() operations media: v4l2-subdev: Add v4l2_subdev_s_stream_helper() function Sakari Ailus (1): media: Add stream to frame descriptor Tomi Valkeinen (21): media: Documentation: mc: add definitions for stream and pipeline media: media-entity.h: add include for min() media: subdev: increase V4L2_FRAME_DESC_ENTRY_MAX to 8 media: mc: entity: Rename streaming_count -> start_count media: v4l2-dev: Add videodev wrappers for media pipelines media: drivers: use video device pipeline start/stop media: drivers: use video_device_pipeline() media: mc: entity: add alloc variant of pipeline_start media: drivers: use video_device_pipeline_alloc_start() media: mc: entity: Add has_pad_interdep entity operation media: mc: convert pipeline funcs to take media_pad media: add V4L2_SUBDEV_FL_STREAMS media: add V4L2_SUBDEV_CAP_STREAMS media: subdev: add v4l2_subdev_has_pad_interdep() media: subdev: add v4l2_subdev_set_routing helper() media: Documentation: add multiplexed streams documentation media: subdev: add stream based configuration media: subdev: use streams in v4l2_subdev_link_validate() media: subdev: add "opposite" stream helper funcs media: subdev: add streams to v4l2_subdev_get_fmt() helper function media: subdev: add v4l2_subdev_set_routing_with_fmt() helper .clang-format | 1 + Documentation/driver-api/media/mc-core.rst | 19 +- .../driver-api/media/v4l2-subdev.rst | 8 + .../userspace-api/media/v4l/dev-subdev.rst | 175 +++ .../userspace-api/media/v4l/user-func.rst | 1 + .../v4l/vidioc-subdev-enum-frame-interval.rst | 5 +- .../v4l/vidioc-subdev-enum-frame-size.rst | 5 +- .../v4l/vidioc-subdev-enum-mbus-code.rst | 5 +- .../media/v4l/vidioc-subdev-g-crop.rst | 5 +- .../media/v4l/vidioc-subdev-g-fmt.rst | 5 +- .../v4l/vidioc-subdev-g-frame-interval.rst | 5 +- .../media/v4l/vidioc-subdev-g-routing.rst | 150 +++ .../media/v4l/vidioc-subdev-g-selection.rst | 5 +- drivers/media/mc/mc-device.c | 13 +- drivers/media/mc/mc-entity.c | 657 +++++++++-- drivers/media/pci/intel/ipu3/ipu3-cio2-main.c | 6 +- .../media/platform/qcom/camss/camss-video.c | 6 +- .../platform/renesas/rcar-vin/rcar-core.c | 5 +- .../platform/renesas/rcar-vin/rcar-dma.c | 18 +- .../media/platform/renesas/vsp1/vsp1_video.c | 6 +- .../platform/rockchip/rkisp1/rkisp1-capture.c | 14 +- .../samsung/exynos4-is/fimc-capture.c | 9 +- .../samsung/exynos4-is/fimc-isp-video.c | 9 +- .../platform/samsung/exynos4-is/fimc-lite.c | 9 +- .../samsung/s3c-camif/camif-capture.c | 6 +- drivers/media/platform/st/stm32/stm32-dcmi.c | 6 +- .../platform/sunxi/sun4i-csi/sun4i_dma.c | 6 +- .../platform/sunxi/sun6i-csi/sun6i_video.c | 6 +- drivers/media/platform/ti/cal/cal-video.c | 6 +- drivers/media/platform/ti/cal/cal.h | 1 -
