+Subject: [PATCH 1295/1295] imx477: Update device tree overlays to support
+ trigger-mode
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Also create generic overrides in camera-mux-N-port, that can be extended
+to configure vsync modes for cameras supporting this.
+
+Example usages (to be combined with camera_auto_detect=0):
+dtoverlay=imx477,cam0,sync-source
+dtoverlay=imx477,sync-sink
+dtoverlay=camera-mux-2port,cam1-imx477,cam1-sync-sink
+dtoverlay=camera-mux-4port,cam3-imx477,cam3-sync-sink
