This driver can also be built as a module. If so, the module will be called pps-ktimer. config PPS_CLIENT_LDISC tristate "PPS line discipline" depends on TTY help If you say yes here you get support for a PPS source connected with the CD (Carrier Detect) pin of your serial port. config PPS_CLIENT_PARPORT tristate "Parallel port PPS client" depends on PARPORT help If you say yes here you get support for a PPS source connected with the interrupt pin of your parallel port. config PPS_CLIENT_GPIO tristate "PPS client using GPIO" help If you say yes here you get support for a PPS source using GPIO. To be useful you must also register a platform device specifying the GPIO pin and other options, usually in your board setup.
