menuconfig PPS_GENERATOR
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.
