include/media/media-entity.h: replace kernel.h with the necessary inclusions

2021-11-09T18:02:49Z

When kernel.h is used in the headers it adds a lot into dependency hell, especially when there are circular dependencies are involved. Replace kernel.h inclusion with the list of what is really being used.

media: entity: Add lockdep check to media graph walk

2021-04-06T12:35:14Z

It was always assumed that walking the media graph would require holding the media_device graph_mutex but this was not documented nor checked for. Add a lockdep check to graph walk init and iter, and document the need for acquiring the graph_mutex. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l2-subdev: handle module refcounting here

2019-03-19T17:29:37Z

The module ownership refcounting was done in media_entity_get/put, but that was very confusing and it did not work either in case an application had a v4l-subdevX device open and the module was unbound. When the v4l-subdevX device was closed the media_entity_put was never called and the module refcount was left one too high, making it impossible to unload it. Since v4l2-subdev.c was the only place where media_entity_get/put was called, just move the functionality to v4l2-subdev.c and drop those confusing entity functions. Store the module in subdev_fh so module_put no longer depends on the media_entity struct. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: v4l2-mc: switch it to use the new approach to setup pipelines

Instead of relying on a static map for pids, use the new sig_type "taint" type to setup the pipelines with the same tipe between different entities. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2: taint pads with the signal types for consumer devices

2018-09-17T17:16:19Z

Consumer devices are provided with a wide different range of types supported by the same driver, allowing different configutations. In order to make easier to setup media controller links, "taint" pads with the signal type it carries. While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries is actually the same as the normal video output. The difference happens at the video/VBI interface: - for VBI, only the hidden lines are streamed; - for video, the stream is usually cropped to hide the vbi lines.
