You could try v4l2-ctl from the v4l-utils package, for example with my 
random cheapo MS webcam, it shows for --list-ctrls option:

...
  focus_absolute (int) : min=0 max=40 step=1 default=0 value=0 
flags=inactive
  focus_auto (bool) : default=0 value=1
...

If it's listed there, you could control it with:

  v4l2-ctl --set-ctrl=focus_auto=1 -d /dev/whatever

Maybe you'll get lucky.
