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.
