media: mc: add debugfs node to keep track of requests

2026-01-05T14:56:31+00:00

Keep track of the number of requests and request objects of a media device. Helps to verify that all request-related memory is freed. Signed-off-by: Hans Verkuil Signed-off-by: Nicolas Dufresne

media: mc: Add nop implementations of media_device_{init,cleanup}

2024-04-10T13:15:30+00:00

To support compilation with Media controller disabled, drivers were required to conditionally call media_device_init and media_device_cleanup. Add nop implementations of both so drivers don't need to care (or at least care less). Signed-off-by: Sakari Ailus Acked-by: Hans Verkuil Signed-off-by: Hans Verkuil

media: mc-device: remove unnecessary __must_check

2023-04-11T16:54:01+00:00

In the file mc-device.c, the function media_device_register_entity_notify() does not need to have the __must_check attribute since it returns only a value of 0. Therefore, we can remove this attribute and change the function's return type. Signed-off-by: Jason Kim Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: mc: entity: Merge media_entity_enum_init and __media_entity_enum_init

2022-09-24T07:10:38+00:00

The media_entity_enum_init() function is a wrapper around __media_entity_enum_init() that turns a media_device pointer argument into the maximum entity ID in the corresponding media graph. __media_entity_enum_init() is never used outside of media_entity_enum_init(), so the two functions can be merged together.

media: mc: Set bus_info in media_device_init()

2022-04-24T07:05:53+00:00

Set bus_info field based on struct device in media_device_init() and remove corresponding code from drivers. Also update media_device_init() documentation: the dev field must be now initialised before calling it. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: mc: Provide a helper for setting bus_info field

2022-04-24T07:04:27+00:00

The bus_info or a similar field exists in a lot of structs, yet drivers tend to set the value of that field by themselves in a determinable way. Thus provide a helper for doing this. To be used in subsequent patches. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: mc: media_device_init() initialises a media_device, not media_entity

2022-04-24T07:02:06+00:00

The documentation for media_device_init() had several references to (struct) media_entity where it should have referred to struct media_device instead. Fix this. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: mc: Remove redundant documentation

2022-04-24T07:01:38+00:00

Remove redundant kerneldoc documentation in mc-device.c. The functions are already documented in media-device.h, where non-redundant documentation is also moved. Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: media-device.h: drop duplicated word in comment

Delete the doubled word "the" in a comment. Signed-off-by: Randy Dunlap Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
