| 556 | By default they are set to inactive (bit value 1) by this driver, |

| 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. |
