11	  If you say yes here you get support for a PPS debugging client
12	  which uses a kernel timer to generate the PPS signal.

14	  This driver can also be built as a module.  If so, the module
15	  will be called pps-ktimer.

34	  If you say yes here you get support for a PPS source using
35	  GPIO. To be useful you must also register a platform device
36	  specifying the GPIO pin and other options, usually in your board
37	  setup.
