This driver can also be built as a module. If so, the module will be called pps-ktimer. config [31mCONFIG_PPS_CLIENT_LDISC[0m tristate "PPS line discipline" depends on [31mCONFIG_TTY[0m help If you say yes here you get support for a [31mCONFIG_PPS[0m source connected with the CD (Carrier Detect) pin of your serial port. config [31mCONFIG_PPS_CLIENT_PARPORT[0m tristate "Parallel port PPS client" depends on [31mCONFIG_PARPORT[0m help If you say yes here you get support for a [31mCONFIG_PPS[0m source connected with the interrupt pin of your parallel port. config [31mCONFIG_PPS_CLIENT_GPIO[0m tristate "PPS client using GPIO" help If you say yes here you get support for a [31mCONFIG_PPS[0m 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. |
