Some PTP Hardware Clocks have input pins that can generate time stamps on the edges of external signals. This functionality can be used in various ways. For example, one can synchronize a PHC device to a global time source by taking a Pulse Per Second signal from the source into the PHC. This patch adds support for synchronizing one or more PHC slaves to a given master clock. The implementation follows a modular design that allows adding different kinds of master clocks in the future. This patch starts off with a single "generic" PPS master, meaning a PPS signal that lacks and time or date information. The generic master assumes that the Linux system time is approximately correct (by NTP or RTC for example) in order to calculate the time of the incoming PPS edges.
