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

36	  If you say yes here you get support for a PPS source using

38	  specifying the GPIO pin and other options, usually in your board
