Subject: libcamera: uvc: Report sensor timestamp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Report the sensor's timestamp in the Request metadata using the
completed buffer timestamp.
The UVC driver reports timestamps of SOE event through metadata, for
which there is no support in the current pipeline implementation.
