  11           PPS (Pulse Per Second) is a special pulse provided by some GPS
  12           antennae. Userland can use it to get a high-precision time
  13           reference.
  14
  15           Some antennae's PPS signals are connected with the CD (Carrier
  16           Detect) pin of the serial line they use to communicate with the
  17           host. In this case use the SERIAL_LINE client support.
  18
  19           Some antennae's PPS signals are connected with some special host
  20           inputs so you have to enable the corresponding client support.

  22           To compile this driver as a module, choose M here: the module
  23           will be called pps_core.ko.

  28         help
  29           Say Y here if you want the PPS support to produce a bunch of debug
  30           messages to the system log.  Select this if you are having a
  31           problem with PPS support and want to see more of what is going on.
