Dual Camera in Rock5b+

Hi.

I use dual IMX219 camera, left one connects to csi 0, right one connects to csi 1.

when use ls -l /dev/video*, there is only one video-camera0, but no video-camera1.

video-camera0 is linked to video31, which is right one.

video22 is left one, but it has not been linked to video-camera1.

so how to fix it.
