Hi Sakari, > The drivers you're looking at are based on register lists so they usually > support just a single frequency.

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? -- Krzysztof "Chris" Hałasa Sieć Badawcza Łukasiewicz Przemysłowy Instytut Automatyki i Pomiarów PIAP Al. Jerozolimskie 202, 02-486 Warszawa
