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 | |
2a1d245b | 32 | * work fine for those chips, except of course for the missing anti-taping |
