I'm reading this on a plane so have no other context and to be honest
I'm struggling to understand what is being discussed here. It would be
really helpful if you were to describe in words what proposed bindings
are intended to do as well as presenting examples, the examples by
themselves require the reader to reverse engineer what the semantics are
intended to be.

As far as I can tell this is proposing adding something to the regulator
binding specifying if users must present either a single value or a
min/target/max triplet. This is obviously problematic since regulators
can be shared - the needs of one user may not match the needs of another
user, and of course most users should not be specifying voltages at all
in the device tree in the first place.
