That alone won't do, I'm afraid. 100ns is a tough target for Linux on a RPi. I'd think in addition to the PPS a 10MHz reference would be needed. I don't see how the Pi can count those in hardware (perhaps its worth to you to use one core for that in rt-linux?). The Beagle Bone {Black, Green, Blue ...} with its PRU is probably the more promising platform for such.
