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? --=20 Krzysztof "Chris" Ha=C5=82asa Sie=C4=87 Badawcza =C5=81ukasiewicz Przemys=C5=82owy Instytut Automatyki i Pomiar=C3=B3w PIAP Al. Jerozolimskie 202, 02-486 Warszawa
