The saa7134 driver
==================
Author Gerd Hoffmann
Card Variations:
----------------
Cards can use either of these two crystals (xtal):
- 32.11 MHz -> .audio_clock=0x187de7
- 24.576MHz -> .audio_clock=0x200000 (xtal * .audio_clock = 51539600)
Some details about 30/34/35:
- saa7130 - low-price chip, doesn't have mute, that is why all those
cards should have .mute field defined in their tuner structure.
- saa7134 - usual chip
- saa7133/35 - saa7135 is probably a marketing decision, since all those
chips identifies itself as 33 on pci.
