I work with these all the time - it's power & data one one pin, and some
kind of a ground. They also make some in 3 terminal packages (pinouts can
be had on the Maxim site). That said, I'm really pleased to see this in
the kernel - as I'm in the process of developing all the firmware to port
one of our product to use Linux! The application guys are way ahead of me,
however...
