Ah, now I see the problem on the RasPi.
These work, when you use just one or the other:
# Uputronics on gpio 18
dtoverlay=pps-gpio,gpiopin=18
# adafruit HAT on gpio 4
dtoverlay=pps-gpio,gpiopin=4
But put use both and you still on get one /dev/ppsX
Also, you would expect this to work, but it also jsut give you one
/dev/ppsX:
dtoverlay=pps-gpio,gpiopin=18,4
So the problem is with the RasPi kernel. Go ahead and nag them for us.
