I execute the command : v4l2-ctl --list-devices
vi-output, ov13b10 2-0036 (platform:15c10000.vi:0):
vi-output, ov7251 2-0060 (platform:15c10000.vi:1):
vi-output, ov7251_l 2-0061 (platform:15c10000.vi:4):
the relationship about device and vi port is not matched what I configured in dtsi. It confused me a lot.
but if only load one camera and set num-channels=1 in its dtsi, the relationship of device and vi port is correct
