| 10 | help | |
| 11 | If you say yes here you get support for a PPS debugging client | |
| 12 | which uses a kernel timer to generate the PPS signal. | |
| 13 | ||
| 14 | This driver can also be built as a module. If so, the module | |
| 15 | will be called pps-ktimer. | |

| 16152045 JN |
33 | help |
| 34 | If you say yes here you get support for a PPS source using | |
| 35 | GPIO. To be useful you must also register a platform device | |
| 36 | specifying the GPIO pin and other options, usually in your board | |
| 37 | setup. |
