thanks for the write-up and examples. I like it a lot and gives driver
maintainers a nice understanding what to do.

While reading through it, I came to think about regulatory_hint(). So is
there a use case where would give it the alpha2 code and the domain
itself at the same time? If not, then it would make more sense to split
this into two functions. Maybe something regulatory_alpha2_hint() and
regulatory_domain_hint(). Just a thought.

Regards

Marcel
