[libcamera-devel] [RFC PATCH v2 5/5] libcamera: pipelines: uvcvideo: add IPAManager

[Paul Elder]

Make the UVC pipeline query for one of the test IPA modules.

Signed-off-by: Paul Elder <paul.elder at ideasonboard.com>

Changes in v2:
- remove IPAManager from PipelineHandler::match parameter

This is a sample of how a IPAManager would be used.
