2022-09-24media: v4l2-ctrls: drop 'elems' argument from control type ops.Hans Verkuil1-17/+11
The type ops for equal, init and validate have an elems argument, but this can be taken from struct v4l2_ctrl: ctrl->elems for equal and init, and ctrl->new_elems for validate (since you are validating a new control value). So drop this argument and update all callers. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2022-07-17media: mc-entity: Add a new helper function to get a remote padLaurent Pinchart1-0/+46
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.

2022-07-17media: v4l2-async: Add notifier operation to destroy asd instancesLaurent Pinchart1-0/+2
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.
