They just take whatever the tuner gives them at a fixed intermediate frequency. It's really the tuner that has the frequency range. I think it would make more sense for the demodulator drivers to fill fe->ops.info.frequency_min|max using fe->ops.tuner_ops.info.frequency_min|max. A frontend driver that doesn't use a separate tuner driver (like DST) would set the fe->ops.info.frequency_min|max directly. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
