Bear in mind Mark that PPS-in via GPIO might not give great results - far too
much jitter
& latency. Some hardware (eg iMX6 boards I have used ) allows PPS-In
to be connected directly to dedicated registers which I found to work well.
(The standard kernel driver needs extensive rework to do this however)
