Hi,

And to also answer another question I missed before:

Do we already have a driver for this? I don't see one in linux-next.

I've a bunch of students form the local university working on a driver
for this, they should submit it real soon now. That does mean that
including this node is a bit premature as the bindings my change, sorry
I overlooked this.

Adding a drivevbus-supply referencing vcc_5v0 so it doesn't
show 0V would be nice.
