| tristate "PPS generators support" |
| help |
| PPS generators are special hardware which are able to produce PPS |
| (Pulse Per Second) signals. |
| |
| To compile this driver as a module, choose M here: the module |
| will be called pps_gen_core. |
| |
| if PPS_GENERATOR |
| |
| config PPS_GENERATOR_DUMMY |
| tristate "Dummy PPS generator (Testing generator, use for debug)" |
| help |
| If you say yes here you get support for a PPS debugging generator |
| (which generates no PPS signal at all). |
| |
| This driver can also be built as a module. If so, the module |
| will be called pps_gen-dummy. |
| |
| config PPS_GENERATOR_PARPORT |
| tristate "Parallel port PPS signal generator" |
| depends on PARPORT && BROKEN |
| help |
| If you say yes here you get support for a PPS signal generator which |
| utilizes STROBE pin of a parallel port to send PPS signals. It uses |
| parport abstraction layer and hrtimers to precisely control the signal. |
