You're going to have to provide a much better explanation of what this
is doing - right now it seems like an abuse of constraints.  Client
drivers can already determine if a particular voltage they want to set
is available via regulator_list_voltage() and so on, that's what
constraints are there to set.  It sounds like you're trying to use them
for something else but you're really not explaining your use case
clearly.
