| * media: Add MIPI CCI register access helper functionsHans de Goede2023-08-102-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CSI2 specification specifies a standard method to access camera sensor registers called "Camera Control Interface (CCI)". This uses either 8 or 16 bit (big-endian wire order) register addresses and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths. Currently a lot of Linux camera sensor drivers all have their own custom helpers for this, often copy and pasted from other drivers. Add a set of generic helpers for this so that all sensor drivers can switch to a single common implementation. These helpers take an extra optional "int *err" function parameter, this can be used to chain a bunch of register accesses together with only a single error check at the end, rather than needing to error check each individual register access. The first failing call will set the contents of err to a non 0 value and all other calls will then become no-ops.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | | | | | | | | | | | The cpia2 driver does not use the vb2 framework for streaming video, instead it implements this in the driver. This is error prone, and nobody stepped in to convert this driver to that framework. The hardware is very old, so the decision was made to remove it altogether.

* media: mc: entity: Rewrite media_pipeline_start()Laurent Pinchart2022-09-241-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Note: the code is mostly from Laurent but the patch description is from Tomi] The media_pipeline_start() and media_pipeline_stop() functions use the media graph walk API to traverse the graph and validate the pipeline. The graph walk traverses the media graph following links between the entities. Also, while the pipeline can't change between the start and stop calls, the graph is walked again from scratch at stop time, or any time a driver needs to inspect the pipeline. With the upcoming multiplexed streams support we will need a bit more intelligent pipeline construction, as e.g. two independent streams may be passing through a single entity via separate pads in which case those pads should not be part of the same pipeline. This patch essentially rewrites the media_pipeline_start/stop so that a pipeline is defined as a set of pads instead of entities and the media graph traversal considers the pad interdependencies when choosing which links to follow. Currently all the entity's pads are considered as interdependent. This means that the behavior with all the current drivers stays the same, but in the future we can define a more fine-grained pipeline construction. Additionally the media pipeline's pads are cached at media_pipeline_start() time, and re-used at media_pipeline_stop() which avoid the need to re-walk the whole graph as the previous implementation did. Also, caching pads in the pipeline can serve in the future as the foundation to provide a better API than the media graph walk to drivers to iterate over pads and entities in the pipeline. Note that the old media_pipeline_start/stop used the media graph walk API. The new version does not use the media graph walk API, but instead a new implementation. There are two reasons for not changing the graph walk: it proved to be rather difficult to change the graph walk to have the features implemented in this patch, and second, this keeps the backward compatibility of the graph walk as there are users of the graph walk API The long term plan is that all the existing code would be converted to use the new cached pipeline, thus allowing us to remove the graph walk.

| | | | | | | | | | | | | | | The newly added media_entity_remote_source_pad_unique() helper function handles use cases where the entity has a link enabled uniqueness constraint covering all pads. There are use cases where the constraint covers a specific pad only. Add a new media_pad_remote_pad_unique() function to handle this. It operates as media_entity_remote_source_pad_unique(), but on a given pad instead of on the entity.

* media: mc-entity: Add a new helper function to get a remote padLaurent Pinchart2022-07-171-1/+2
| | | | | | | | | | | | | | | | | | | | | The media_entity_remote_pad_first() helper function returns the first remote pad it finds connected to a given pad. Beside being possibly non-deterministic (as it stops at the first enabled link), the fact that it returns the first match makes it unsuitable for drivers that need to guarantee that a single link is enabled, for instance when an entity can process data from one of multiple sources at a time. For those use cases, add a new helper function, media_entity_remote_pad_unique(), that operates on an entity and returns a remote pad, with a guarantee that only one link is enabled. To ease its use in drivers, also add an inline wrapper that locates source pads specifically. A wrapper that locates sink pads can easily be added when needed.

* media: v4l2-async: Add notifier operation to destroy asd instancesLaurent Pinchart2022-07-171-0/+6
| | | | | | | | | | | | | | | | | | | Drivers typically extend the v4l2_async_subdev structure by embedding it in a driver-specific structure, to store per-subdev custom data. The v4l2_async_subdev instances are freed by the v4l2-async framework, which makes this mechanism cumbersome to use safely when custom data needs special treatment to be destroyed (such as freeing additional memory, or releasing references to kernel objects). To ease this, add a .destroy() operation to the v4l2_async_notifier_operations structure. The operation is called right before the v4l2_async_subdev is freed, giving drivers a chance to destroy data if needed.
