so would this do a complete dt search for every regulator?

Yes, with the first param being NULL, tthe entire device tree will be
searched.

we would also need the driver names and dt names to match for this to
work, right?

Driver name does not matter.  The key for this search to work is having
regulator's name (regulator_desc->name) match device tree node's name,
case ignored.

Mark, whats your take on this? I am somehow not quite sure if we should
have this limitation put in to match DT node names with whats in the
driver structs (regulator_desc).

This looks wrong to me.  Matching based on node /name/, particularly
when searching the entire tree, will cause problems.

Okay, it's wrong then since so many people say it's wrong :)  I guess
a quick fix would be adding one property in device tree node for
matching some unique field in regulator_desc, id, maybe?  Mark, any
suggestion?
