a strobe is lightning up when doing the following ( stop_strobe needs to be set for "strobe" to work again ):

v4l2-ctl --media-bus-info platform:30b80000.csi --device white:torch --set-ctrl led_mode=1
v4l2-ctl --media-bus-info platform:30b80000.csi --device white:torch --set-ctrl strobe=
v4l2-ctl --media-bus-info platform:30b80000.csi --device white:torch --set-ctrl stop_strobe=

turn on torch:

v4l2-ctl --media-bus-info platform:30b80000.csi --device white:torch --set-ctrl led_mode=2

turn off torch:

v4l2-ctl --media-bus-info platform:30b80000.csi --device white:torch --set-ctrl led_mode=0

but not sure if this is enough testing, but I guess the application will directly do the above, in which case it would be ok.
