From 47c53f8084ed9e6e40cd2f8f74415472ccccef9c Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 20 Nov 2022 19:20:30 +0200 Subject: pipeline: imx8-isi: Set SensorTimestamp metadata Report the sensor timestamp in metadata. Use the timestamp from the first buffer. Accuracy could be improved by using the frame start event from the CSI-2 receiver, but the kernel driver doesn't support it yet.
