+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.
