The tuner's datasheet. Assuming the tuner is fairly standard (and since
tuner type 57 seems to work I think this is a reasonable assumption),
the information that is needed can be found in tuner.c (or
tuner-simple.c in the kernel), struct tunertype:
unsigned short thresh1; /* band switch VHF_LO <=> VHF_HI */
unsigned short thresh2; /* band switch VHF_HI <=> UHF */
unsigned char VHF_L; /* band switch byte, low band */
unsigned char VHF_H; /* band switch byte, mid band */
unsigned char UHF; /* band switch byte, high band */
unsigned char config; /* config byte, aka control byte */
This info comes from the datasheet.
