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. | |

35 | help |
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. | |
