12697fb85fSRodolfo Giometti	  If you say yes here you get support for a PPS debugging client
13697fb85fSRodolfo Giometti	  which uses a kernel timer to generate the PPS signal.

15697fb85fSRodolfo Giometti	  This driver can also be built as a module.  If so, the module
16697fb85fSRodolfo Giometti	  will be called pps-ktimer.
