[libcamera-devel] [PATCH 0/3] libcamera: Add new Camera devices property

[Kieran Bingham]

It can be beneficial to allow reporting the devices used by a camera to
facilitate de-duplication of resources when handling cameras from a
centralised infrastructure such as PipeWire.

Expose a new property on all cameras which reports a list of dev_t
values representing devices used by the camera.

Pipelines supported by media-controller will automatically register an
entry for any video node present in the media graphs registered with the
Pipeline Handler.

Kieran Bingham (3):
  libcamera: controls: Support dev_t in an Integer32 type.
  libcamera: properties: Provide a Devices camera property
  libcamera: pipeline: Register device numbers with camera
