	SKIP=10

	media-ctl -d "platform:30a90000.csi" --set-v4l2 "'csi':0 [fmt:SGBRG10/${WIDTH}x${HEIGHT} colorspace:raw]"
	media-ctl -d "platform:30a90000.csi" --set-v4l2 "'imx8mq-mipi-csi2 30a70000.csi':0 [fmt:SGBRG10/${WIDTH}x${HEIGHT} colorspace:raw]"
	media-ctl -d "platform:30a90000.csi" --set-v4l2 "'hi846 2-0020':0 [fmt:SGBRG10/${WIDTH}x${HEIGHT} colorspace:raw]"
	media-ctl -d "platform:30a90000.csi" -l "'hi846 2-0020':0 -> 'imx8mq-mipi-csi2 30a70000.csi':0 [1]"
