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

GPIO. To be useful you must also register a platform device
|
|
specifying the GPIO pin and other options, usually in your board
|
|
setup.
