| * media: cx88: add IR remote support for NotOnlyTV LV3HDaniel González Cabanelas2022-09-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI hybrid card NotOnlyTV LV3H has a built-in IR receiver connected via I2C bus, currently not supported. This receiver is probably present in more Geniatech cards. It has no capability for repeating when a key is held down. Add support for this built-in IR receiver. Use the existing Total Media In Hand_02 remote keytable (Geniatech Mygica X8507) which matches exactly the LV3H remote.

| * media: mc: entity: Rewrite media_pipeline_start()Laurent Pinchart2022-09-241-6/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new variant of media_pipeline_start(), media_pipeline_alloc_start(). media_pipeline_alloc_start() can be used by drivers that do not need to extend the media_pipeline. The function will either use the pipeline already associated with the entity, if such exists, or allocate a new pipeline. When media_pipeline_stop() is called and the pipeline's use count drops to zero, the pipeline is automatically freed.

| * media: v4l2-dev: Add videodev wrappers for media pipelinesTomi Valkeinen2022-09-241-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the upcoming stream related improvements to the pipelines, the pipelines are moved from media entities to media pads. As the drivers currently use the pipelines with the entity based model, moving the pipelines to pads will cause changes to the drivers. However, most of the uses of media pipelines are related to a video device (a DMA engine) with a single pad, and thus there's never a need to support multiple pads in these use cases. We can avoid pushing the complexities of the pad based model to the drivers by adding video device wrappers for the pipeline related functions. This patch adds a number of wrappers to media_pipeline functions, all of which take a video_device as a parameter (instead of a media_entity), and verify that there's just one pad.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | V4L2_FRAME_DESC_ENTRY_MAX is currently set to 4. In theory it's possible to have an arbitrary amount of streams in a single pad, so preferably there should be no hardcoded maximum number. However, I believe a reasonable max is 8, which would cover a CSI-2 pad with 4 streams of pixel data and 4 streams of metadata.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
