13 | * Copyright (C) 1999 Nathan Laredo <laredo@gnu.org> | |

29 | * Note: the saa7126 is identical to the saa7127, and the saa7128 is | |
30 | * identical to the saa7129, except that the saa7126 and saa7128 have | |
31 | * macrovision anti-taping support. This driver will almost certainly | |
32 | * work find for those chips, except of course for the missing anti-taping | |
33 | * support. | |
