Ideally, what's provided by the demod and not the tuner max/min. The tuners max/min should be checked by the demod on setting params. The upper/lower limits in the demodulator drivers, came from the concept of a frontend as a whole. Independant bounds do not make sense (except internally -- It is the demod driver that which sets parameters for the tuner. The external world doesn't need to know what's the limit of the tuner, but only of the frontend as a whole). Ideally, the demodulator should just demodulate only. There are some cases, there are some cases which are not.
