media: mc: Rename pad as origin in __media_pipeline_start()

2024-11-07T08:05:58Z

Rename the pad field in __media_pipeline_start() to both better describe what it is and avoid masking it during the loop. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Hans Verkuil

media: mc: Add num_links flag to media_pad

2024-02-05T13:29:34Z

Maintain a counter of the links connected to a pad in the media_pad structure. This helps checking if a pad is connected to anything, which will be used in the pipeline building code.

media: mc: Make media_get_pad_index() use pad type flag

2023-05-25T14:21:22Z

Use the pad flag specifying the pad type instead of a boolean in preparation for internal source pads. Also make the loop variable unsigned. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Hans Verkuil

media: mc: Make media_entity_get_fwnode_pad() fwnode argument const

2023-05-25T14:21:21Z

fwnode_graph_parse_endpoint() fwnode argument is now const, therefore make media_entity_get_fwnode_pad() fwnode argument const as well. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: mc: entity: Add entity iterator for media_pipeline

2023-02-06T07:33:44Z

Add a media_pipeline_for_each_entity() macro to iterate over entities in a pipeline. This should be used by driver as a replacement of the media_graph_walk API, as iterating over the media_pipeline uses the cached list of pads and is thus more efficient. Deprecate the media_graph_walk API to indicate it shouldn't be used in new drivers. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: mc: Improve the media_entity_has_pad_interdep() documentation

2023-01-22T08:25:11Z

Document the function parameters, the requirements on the pad0 and pad1 arguments, the locking requirements and the return value. Also improve the documentation of the corresponding .has_pad_interdep() operation, stating clearly that the operation must be called through the media_entity_has_pad_interdep() function only.

media: mc: convert pipeline funcs to take media_pad

Now that the pipeline is stored into pads instead of entities, we can change the relevant functions to take pads instead of entities. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
