Redesign tuners struct for maximum flexibility
From: Michael Krufky <mkrufky@m1k.net>
- tunertype struct redefined to allow one or more tuner_params structs
per tuner definition, one for each video standard.
- Each tuner_params struct has an element containing an arbitrary
amount of tuner_ranges.
(this is needed for dvb tuners - to be handled later)
- A tuner_range may be referenced by multiple tuner_params structs.
There are many duplicates in here. Reusing tuner_range structs,
rather than defining new ones for each tuner, will cut down on
memory usage, and is preferred when possible.
- tunertype struct contains an element, has_tda988x.
We must set this for all tunertypes that contain a tda988x
chip, and then we can remove this setting from the various
card structs.
- Improves tuners array memory usage efficiency.
- Right now, all tuners are using the first tuner_params[] array element
for analog mode. In the future, we will be merging similar tuner
definitions together, such that each tuner definition will have a
tuner_params struct for each available video standard. At that point,
the tuner_params[] array element will be chosen based on the video
standard in use.
