I currently have a camera that will output 4 captured data to 4 virtual channels through a csi interface. I refer to the device tree configuration of imx390, only /dev/video0 appears, but /dev/video1 /dev/video2 /dev/video3 does not appear
The device tree is as follows, please help to check for errors:
