[libcamera-devel] [PATCH v3 09/14] libcamera: ipu3: Register camera controls

[Jacopo Mondi]

Register controls for the IPU3 pipeline handler. The only supported
Camera control is currently the pipeline depth control.

Report the minimum and maximum values the pipeline handler supports
for the pipeline processing stages.
