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