Dear all,
We have facing problem when try to support multi cameras on 28.2 kernel version. On 28.1 kernel version, 3 cameras could display as well (/dev/video0, /dev/video1, /dev/video2) with below dtb file

But on 28.2 kernel version, only one camera has been seen (/dev/video0). I make sure that camera probe function has been called and finished 3 times by console log.
