I figured it might be something like this :-). I've added the vdd-supply
binding in v5.

If this isn't something that can be easily handled in the core, do you
think we can document it somewhere as a convention/common idiom?
(Assuming it's not already documented, of course). It seems like it's
something that all IIO devices would need. I can do the writing part.

Thanks,
