Its a sensor on an embedded board, it might be managing the backlight or
measuring the dirt level in a sewage pipe depending upon application.

Its easy enough to make it an input device but that would then end up
with polled_input_dev which keeps waking up and costs battery. A lot of
the polled input model is somewhat broken in that regard but I can see
Linus point.

Looks like goes into misc for the moment with all the other light sensors
and I'll see if I can merge it with the 29007 support while I am at it.
