Does that mean that drivers supporting a frequency range (rather than a
single frequency) don't need the range (nor single frequency) in DT?

While it's true that the AR0521 driver can (and has to) work with
different frequencies (on different systems), I think I can specify
a single frequency per system. But - should I really do that?
