6 menuconfig PPS_GENERATOR
7 tristate "PPS generators support"
9 PPS generators are special hardware which are able to produce PPS
10 (Pulse Per Second) signals.
12 To compile this driver as a module, choose M here: the module
13 will be called pps_gen_core.
17 config PPS_GENERATOR_DUMMY
18 tristate "Dummy PPS generator (Testing generator, use for debug)"
20 If you say yes here you get support for a PPS debugging generator
21 (which generates no PPS signal at all).
23 This driver can also be built as a module. If so, the module
24 will be called pps_gen-dummy.
26 config PPS_GENERATOR_PARPORT
27 tristate "Parallel port PPS signal generator"
28 depends on PARPORT && BROKEN
30 If you say yes here you get support for a PPS signal generator which
31 utilizes STROBE pin of a parallel port to send PPS signals. It uses
32 parport abstraction layer and hrtimers to precisely control the signal.
