From 3ac86ff8bf7e7d0c5857990a2d0a7148b6e48a71 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 1 Mar 2024 18:45:29 +0200 Subject: pipeline: raspberrypi: vc4: Fix configuration of the embedded data node The Unicam embedded data video device suffers from two issues with the upstream driver: - The driver uses the generic metadata V4L2_META_FMT_GENERIC_* formats, instead of the downstream V4L2_META_FMT_SENSOR_DATA. - The driver requires the width and height of the embedded data stream to be configured. Fix them both.
