2023-08-10media: v4l: async: Set v4l2_device and subdev in async notifier initSakari Ailus2-29/+19
Set the v4l2_device already in async notifier init, so struct device related to it will be available before the notifier is registered. This requires separating notifier initialisation into two functions, one that takes v4l2_device as its argument, v4l2_async_nf_init and v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the notifier will use a single function, v4l2_async_nf_register. This is done in order to make struct device available earlier, during construction of the async connections, for sensible debug prints.

2023-07-28media: v4l: async: Allow multiple connections between entitiesSakari Ailus1-73/+76
When the v4l2-async framework was introduced, the use case for it was to connect a camera sensor with a parallel receiver. Both tended to be rather simple devices with a single connection between them. The framework has been since improved in multiple ways but there are limitations that have remained, for instance the assumption an async sub-device is connected towards a single notifier and via a single link only. This patch enables connecting a sub-device to one or more notifiers simultaneously, with one or more connections per notifier. The notifier information is moved from the sub-device to the connection and the connections in sub-device are no longer a pointer but a linked list.

2023-07-28media: v4l: async: Rework internal listsSakari Ailus1-48/+54
This patch re-arranges internal V4L2 async lists for preparation of supporting multiple connections per sub-device as well as cleaning up used lists. The list of unbound V4L2 sub-devices shall be maintained for the purpose of listing those sub-devices only, not for their bindin status. Also, the V4L2 async connections now have, instead of two list entries, a single list entry in the notifier's list, be that either waiting or done lists, while the notifier's asc_list is removed. The one-to-one relation between a sub-device and a connection is still maintained in this patch.

2023-07-28media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connectionSakari Ailus2-84/+83
Rename v4l2_async_subdev as v4l2_async_connection, in order to differentiate between the sub-devices and their connections: one sub-device can have many connections but the V4L2 async framework has so far allowed just a single one. Connections in this context will later translate into either MC ancillary or data links. This patch prepares changing that relation by changing existing users of v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices themselves will not be needed anymore Additionally, __v4l2_async_nf_add_subdev() has been renamed __v4l2_async_nf_add_connection().

2023-07-28media: v4l: async: Simplify async sub-device fwnode matchingSakari Ailus1-67/+21
V4L2 async sub-device matching originally used the device nodes only. Endpoint nodes were taken into use instead as using the device nodes was problematic for it was in some cases ambiguous which link might have been in question. There is however no need to use endpoint nodes on both sides, as the async sub-device's fwnode can always be trivially obtained using fwnode_graph_get_remote_endpoint() when needed while what counts is whether or not the link is between two device nodes, i.e. the device nodes match. This will briefly break the adv748x driver but it will be fixed later in the set, by patch "media: adv748x: Return to endpoint matching".

The v4l2_async_nf_parse_fwnode_endpoints() function, part of v4l2-fwnode.c, was a helper meant to register one async sub-dev for each fwnode endpoint of a device. The function is marked as deprecated in the documentation and is actually not used anywhere anymore. Drop it and remove the helper function v4l2_async_nf_fwnode_parse_endpoint() from v4l2-fwnode.c. This change allows to make the helper function __v4l2_async_nf_add_connection() visibility private to v4l2-async.c so that there is no risk drivers can mistakenly use it.

2023-04-15media: v4l2-subdev: Add new ioctl for client capabilitiesTomi Valkeinen1-0/+63
Add new ioctls to set and get subdev client capabilities. Client in this context means the userspace application which opens the subdev device node. The client capabilities are stored in the file handle of the opened subdev device node, and the client must set the capabilities for each opened subdev. For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which indicates that the client is streams-aware. The reason for needing such a flag is as follows: Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain reserved fields (usually a single array field). These reserved fields can be used to extend the ioctl. The userspace is required to zero the reserved fields. We recently added a new 'stream' field to many of these structs, and the space for the field was taken from these reserved arrays. The assumption was that these new 'stream' fields are always initialized to zero if the userspace does not use them. This was a mistake, as, as mentioned above, the userspace is required to zero the _reserved_ fields. In other words, there is no requirement to zero this new stream field, and if the userspace doesn't use the field (which is the case for all userspace applications at the moment), the field may contain random data. This shows that the way the reserved fields are defined in v4l2 is, in my opinion, somewhat broken, but there is nothing to do about that. To fix this issue we need a way for the userspace to tell the kernel that the userspace has indeed set the 'stream' field, and it's fine for the kernel to access it. This is achieved with the new ioctl, which the userspace should usually use right after opening the subdev device node.

When an async notifier is unregistered, the async sub-devices in the notifier's done list will disappear with the notifier. However this is currently also done to the sub-notifiers that remain registered. Their sub-devices only need to be unbound while the async sub-devices themselves need to be returned to the sub-notifier's waiting list. Do this now.

2023-03-20media: subdev: Add V4L2_SUBDEV_ROUTING_NO_MULTIPLEXINGTomi Valkeinen1-3/+33
A common case with subdev routing is that on the subdevice just before the DMA engines (video nodes), no multiplexing is allowed on the source pads, as the DMA engine can only handle a single stream. In some other situations one might also want to do the same check on the sink side. Add new routing validation flags to check these: V4L2_SUBDEV_ROUTING_NO_SINK_MULTIPLEXING and V4L2_SUBDEV_ROUTING_NO_SOURCE_MULTIPLEXING.

2023-03-20media: subdev: Split V4L2_SUBDEV_ROUTING_NO_STREAM_MIXTomi Valkeinen1-4/+11
V4L2_SUBDEV_ROUTING_NO_STREAM_MIX routing validation flag means that all routes from a sink pad must go to the same source pad and all routes going to the same source pad must originate from the same sink pad. This does not cover all use cases. For example, if a device routes all streams from a single sink pad to any of the source pads, but streams from multiple sink pads can go to the same source pad, the current flag is too restrictive. Split the flag into two parts, V4L2_SUBDEV_ROUTING_NO_SINK_STREAM_MIX and V4L2_SUBDEV_ROUTING_NO_SOURCE_STREAM_MIX, which add the restriction only on one side of the device. Together they mean the same as V4L2_SUBDEV_ROUTING_NO_STREAM_MIX.
