404b32fb | 2 | * saa711x - Philips SAA711x video decoder driver version 0.0.1 |
340622c5 | 3 | * |
404b32fb MCC |
4 | * To do: Now, it handles only saa7113/7114. Should be improved to |
5 | * handle all Philips saa711x devices. | |
340622c5 | 6 | * |
404b32fb | 7 | * Based on saa7113 driver from Dave Perks <dperks@ibm.net> |
