V3 available at: https://patchwork.kernel.org/cover/10839889/ V2 sent by Niklas is available at: https://patchwork.kernel.org/cover/10573817/ Series available at: git://jmondi.org/linux v4l2-mux/media-master/v4 Few changes compared to v3: - Rebased on latest media master - Include Sakari's and Luca's comments on documentation patch - Improve connected pad operator as suggested by Ian and Sakari - Fix a bogus -EINVAL return in 31/31 as suggested by Sakari - Improve adv748x afe has_route as suggested by Luca and Sakari - Closed some checkpatch warnings (there are still a few though) v2 -> v3 - Added IOCTLs documentation, and a section to describe multiplexed media links to the v4l2-subdevice interface chapter and expanded functions documentation - Re-worked the IOCTLs so that they don't need a compat version - Sort pads to be passed to has_route() by their index values - Drop indirect routes support from this initial version. Might be considered later to simplify subdevice drivers implementations - Add has_route() operations to adv748x and rcar-csi2 subdevice drivers Jacopo Mondi (4): media: entity: Add iterator helper for entity pads media: Documentation: Add GS_ROUTING documentation adv748x: afe: Implement has_route() media: rcar-csi2: Implement has_route() Laurent Pinchart (4): media: entity: Add has_route entity operation media: entity: Add media_entity_has_route() function media: entity: Use routing information during graph traversal v4l: subdev: Add [GS]_ROUTING subdev ioctls and operations Niklas Söderlund (7): adv748x: csi2: add translation from pixelcode to CSI-2 datatype adv748x: csi2: only allow formats on sink pads adv748x: csi2: describe the multiplexed stream adv748x: csi2: add internal routing configuration adv748x: afe: add routing support rcar-csi2: use frame description information to configure CSI-2 bus rcar-csi2: expose the subdevice internal routing Sakari Ailus (16): media: entity: Use pad as a starting point for graph walk media: entity: Use pads instead of entities in the media graph walk stack media: entity: Walk the graph based on pads v4l: mc: Start walk from a specific pad in use count calculation media: entity: Move the pipeline from entity to pads media: entity: Use pad as the starting point for a pipeline media: entity: Skip link validation for pads to which there is no route to media: entity: Add an iterator helper for connected pads media: entity: Add only connected pads to the pipeline media: entity: Add debug information in graph walk route check v4l: Add bus type to frame descriptors v4l: Add CSI-2 bus configuration to frame descriptors v4l: Add stream to frame descriptor v4l: subdev: Take routing information into account in link validation v4l: subdev: Improve link format validation debug messages v4l: mc: Add an S_ROUTING helper function for power state changes Documentation/media/kapi/mc-core.rst | 15 +- Documentation/media/uapi/v4l/dev-subdev.rst | 92 ++++++ Documentation/media/uapi/v4l/user-func.rst | 1 + .../uapi/v4l/vidioc-subdev-g-routing.rst | 139 ++++++++ drivers/media/i2c/adv748x/adv748x-afe.c | 91 ++++++ drivers/media/i2c/adv748x/adv748x-csi2.c | 136 +++++++- drivers/media/i2c/adv748x/adv748x.h | 1 + drivers/media/media-device.c | 13 +- drivers/media/media-entity.c | 238 ++++++++------ drivers/media/pci/intel/ipu3/ipu3-cio2.c | 6 +- .../media/platform/exynos4-is/fimc-capture.c | 8 +- .../platform/exynos4-is/fimc-isp-video.c | 8 +- drivers/media/platform/exynos4-is/fimc-isp.c | 2 +- drivers/media/platform/exynos4-is/fimc-lite.c | 10 +- drivers/media/platform/exynos4-is/media-dev.c | 20 +- drivers/media/platform/omap3isp/isp.c | 2 +- drivers/media/platform/omap3isp/ispvideo.c | 25 +- drivers/media/platform/omap3isp/ispvideo.h | 2 +- .../media/platform/qcom/camss/camss-video.c | 6 +- drivers/media/platform/rcar-vin/rcar-core.c | 16 +- drivers/media/platform/rcar-vin/rcar-csi2.c | 220 ++++++++++--- drivers/media/platform/rcar-vin/rcar-dma.c | 8 +- .../media/platform/s3c-camif/camif-capture.c | 6 +- drivers/media/platform/vimc/vimc-capture.c | 5 +- drivers/media/platform/vsp1/vsp1_video.c | 18 +- drivers/media/platform/xilinx/xilinx-dma.c | 20 +- drivers/media/platform/xilinx/xilinx-dma.h | 2 +- drivers/media/usb/au0828/au0828-core.c | 4 +- drivers/media/v4l2-core/v4l2-ioctl.c | 25 +- drivers/media/v4l2-core/v4l2-mc.c | 76 +++-- drivers/media/v4l2-core/v4l2-subdev.c | 296 ++++++++++++++++-- .../staging/media/davinci_vpfe/vpfe_video.c | 47 +-- drivers/staging/media/imx/imx-media-utils.c | 8 +- drivers/staging/media/omap4iss/iss.c | 2 +- drivers/staging/media/omap4iss/iss_video.c | 38 +-- drivers/staging/media/omap4iss/iss_video.h | 2 +- include/media/media-entity.h | 143 ++++++--- include/media/v4l2-mc.h | 22 ++ include/media/v4l2-subdev.h | 49 +++ include/uapi/linux/v4l2-subdev.h | 40 +++ 40 files changed, 1492 insertions(+), 370 deletions(-) create mode 100644 Documentation/media/uapi/v4l/vidioc-subdev-g-routing.rst --- 2.21.0
