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, Alex
