media: mc-entity: Drop ifdef for media_entity_cleanup definition

2026-05-21T05:41:32+00:00

The media_entity_cleanup() function is defined in media-entity.h as a static inline no-op when CONFIG_MEDIA_CONTROLLER is enabled, and as a no-op macro otherwise. This complexity is unneeded. Use a static inline function in all cases.

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

2024-11-07T08:05:58+00:00

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

2024-02-05T13:29:34+00:00

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: entity: Add entity iterator for media_pipeline

2023-02-06T07:33:44+00:00

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
