        /dev/video7
        /dev/video8
        /dev/video16
        /dev/video17

rkisp_mainpath (platform:rkisp-vir0):
        /dev/video0
        /dev/video1
        /dev/video2
        /dev/video3
        /dev/video4
        /dev/video5
        /dev/video6

rkisp_mainpath (platform:rkisp-vir1):
        /dev/video9
        /dev/video10
        /dev/video11
        /dev/video12
        /dev/video13
