555 These settings tend to depend on the specifics of the board.
556 By default they are set to inactive (bit value 1) by this driver,
557 overwriting any changes made by the tvnorm. This means that it
558 is the responsibility of the module using the tda9887 to set
559 these values in case of changes in the tvnorm.
560 In many cases port 2 should be made active (0) when selecting
561 SECAM-L, and port 2 should remain inactive (1) for SECAM-L'.
562
563 For the other standards the tda9887 application note says that
564 the ports should be set to active (0), but, again, that may
565 differ depending on the precise hardware configuration.
