Steve Longerbeam authored
The entities external to the i.MX6 IPU and i.MX7 now create the links to their fwnode-endpoint connected entities in their notifier bound callbacks. Which means imx_media_create_of_links() and imx_media_create_csi_of_links() are no longer needed and are removed. However there is still one case in which imx-media needs to create fwnode-endpoint based links at probe completion. The v4l2-async framework does not allow multiple subdevice notifiers to contain a duplicate subdevice in their asd_list. Only the first subdev notifier that discovers and adds that one subdevice to its asd_list will receive a bound callback for it. Other subdevices that also have firmware endpoint connections to this duplicate subdevice will not have it in their asd_list, and thus will never receive a bound callback for it. In the case of imx-media, the one duplicate subdevice in question is the i.MX6 MIPI CSI-2 receiver. Until there is a solution to that problem, rewrite imx_media_create_links() to add the missing links from the CSI-2 receiver to the CSIs and CSI muxes. The function is renamed imx_media_create_csi2_links(). Signed-off-by:

Fix the 1:1 port-id:pad-index assumption for the upstream subdevice, by searching the upstream subdevice's endpoints for one that maps to the pad's index. This is carried out by a new reverse mapping function imx_media_get_pad_fwnode(). Signed-off-by:

For i.MX5/6, if the bound subdev is a video mux, it must be one of the CSI muxes, and for i.MX7, the bound subdev must always be a CSI mux. So if the bound subdev is a video mux, mark it as a CSI mux with a new group id IMX_MEDIA_GRP_ID_CSI_MUX. In the process use the new group id in csi_get_upstream_endpoint(), and do some cleanup in that function for better readability. Suggested-by:

The function imx7_csi_get_upstream_endpoint() is not necessary for imx7. First, the imx7 CSI only receives from the CSI mux, so much of the code in there is pointless. Second, it is only used to determine whether the CSI mux has selected the CSI-2 input or the parallel input. This can be accomplished much more simply by getting the function type of selected input entity to the CSI mux. Signed-off-by:

The CSI does not have a 1:1 relationship between fwnode port numbers and pad indexes. In fact the CSI fwnode device is itself a port which is the sink, containing only a single fwnode endpoint. Implement media_entity operation get_fwnode_pad to first verify the given endpoint is the CSI's sink endpoint, and if so return the CSI sink pad index. Signed-off-by:

media: Revert "media: v4l2-fwnode: Add a convenience function for registering subdevs with notifiers" The users of v4l2_async_register_fwnode_subdev() have switched to parsing their endpoints and setting up async sub-device lists in their notifiers locally, without using the endpoint parsing callbacks. There are no more users of v4l2_async_register_fwnode_subdev() so this convenience function can be removed. This reverts commit 1634f0ed. Signed-off-by:

Instead of using the convenience functions v4l2_async_notifier_parse_fwnode_endpoints*() or v4l2_async_register_fwnode_subdev(), parse the input endpoints and set up the async sub-devices without using callbacks. The drivers know which ports it must parse and how to handle unconnected remotes, so it makes the code simpler to transfer control of endpoint parsing to the driver. Signed-off-by:

Add functions to create media links between source and sink subdevices, based on the fwnode endpoint connections between them: v4l2_create_fwnode_links_to_pad() - create links from a source subdev to a single sink pad based on fwnode endpoint connections. v4l2_create_fwnode_links() - create all links from a source to sink subdev based on fwnode endpoint connections. These functions can be used in a sink's v4l2-async notifier subdev bound callback to make the links from the bound subdev. Signed-off-by: -

Since its inclusion in v3.9, no users of the SuperH VEU mem2mem video processing driver have appeared upstream. All VEU devices in SuperH board code still bind to the "uio_pdrv_genirq" driver instead. The original author marked the driver orphaned in v3.15. Remove the driver; it can always be resurrected from git history when needed. Signed-off-by:

Hans Verkuil authored
While normal video/radio/vbi/swradio nodes have a proper QUERYCAP ioctl that apps can call to determine that it is indeed a V4L2 device, there is currently no equivalent for v4l-subdev nodes. Adding this ioctl will solve that, and it will allow utilities like v4l2-compliance to be used with these devices as well. SUBDEV_QUERYCAP currently returns the version and capabilities of the subdevice. Define a capability flag to report if the subdevice is registered in read-only mode. Signed-off-by:

A sub-device device node can be registered in user space only if the CONFIG_VIDEO_V4L2_SUBDEV_API Kconfig option is selected. Currently the open/close file operations and the ioctl handler have some parts of their implementations guarded by #if defined(CONFIG_VIDEO_V4L2_SUBDEV_API), while they are actually not accessible without a video device node registered to user space. Guard the whole open, close and ioctl handler and provide stubs if the VIDEO_V4L2_SUBDEV_API Kconfig option is not selected. This slightly reduces the kernel size when the option is not selected and simplifies the file ops and ioctl implementations. Signed-off-by:
