[libcamera-devel] [PATCH v1 6/6] libcamera: pipeline: ipu3: Pass request metadata to IPA

[Umang Jain]

From: Kieran Bingham <kieran.bingham at ideasonboard.com>

Pass the request metadata control list to the IPA when setting
passing the statistics buffers, or after the raw buffer completion.

This allows us to pass in the timestamp and other data from the request
which will be used by the IPA.
