| 11 | help |
| 12 | If you say yes here you get support for a PPS debugging client |
| 13 | which uses a kernel timer to generate the PPS signal. |
| 14 | |
| 15 | This driver can also be built as a module. If so, the module |
| 16 | will be called pps-ktimer. |

| 36 | If you say yes here you get support for a PPS source using |
| 37 | GPIO. To be useful you must also register a platform device |
| 38 | specifying the GPIO pin and other options, usually in your board |
| 39 | setup. |
