PPS-GPIO

Question 
Hello Forum,

i want to set up a stratum 1 server on the pine, with the Adafruit GPS-Board. On the Pi it's no problem, because i don't need to make big changes.

What I have done so far on pine:
Code:
$ git clone --depth 1 --single-branch -b pine64-hacks-1.2 https://github.com/longsleep/linux-pine64
$ curl -sSL https://github.com/longsleep/build-pine64-image/raw/master/blobs/pine64.dts > linux-pine64/arch/arm64/boot/dts/sun50i-a64-pine64-plus.dts
$ make menuconfig

The pps-part in the config looks like this:
Code:
#
# PPS support
#
CONFIG_PPS=m
CONFIG_PPS_DEBUG=y

#
# PPS clients support
#
CONFIG_PPS_CLIENT_KTIMER=m
CONFIG_PPS_CLIENT_LDISC=m
CONFIG_PPS_CLIENT_PARPORT=m
CONFIG_PPS_CLIENT_GPIO=m

#
# PPS generators support
#
After build dmesg shows:

Code:
# dmesg | grep pps
[   14.067625] pps_core: LinuxPPS API ver. 1 registered
[   14.092242] pps_core: Software ver. 5.3.6 - Copyright 2005-2007 Rodolfo Giometti <giometti@linux.it>

But where the pin is defined?
The pps-source is connected to Pin 18 on the board.
That's all what I have found:
https://www.kernel.org/doc/Documentation...s-gpio.txt
https://dev.openwrt.org/browser/trunk/ta...?rev=44392

For me that sounds like rocket science. :/

Could somebody "take me by the hand" please, and tell me what is the next step?



(And please, excuse my bad english.)
