518 By default they are set to inactive (bit value 1) by this driver,

520 is the responsibility of the module using the tda9887 to set
521 these values in case of changes in the tvnorm.
522 In many cases port 2 should be made active (0) when selecting
523 SECAM-L, and port 2 should remain inactive (1) for SECAM-L'.
524
525 For the other standards the tda9887 application note says that
526 the ports should be set to active (0), but, again, that may
527 differ depending on the precise hardware configuration.
