+ will be called pps-ktimer.

+ with the CD (Carrier Detect) pin of your serial port.
+
+config PPS_CLIENT_PARPORT
+ tristate "Parallel port PPS client"
+ depends on PARPORT

+config PPS_CLIENT_GPIO
+ tristate "PPS client using GPIO"

+ specifying the GPIO pin and other options, usually in your board
+ setup.
