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.

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.
