Those pin defintion's are tied to the PocketBeagle..
For the older BeagleBone use this example for the usart pis
https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-UART1-00A0.dts#L36-L66
and expand that for P9_12, look at P8_26 here for help:
https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-RTC-01-00A0.dts#L39
https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-RTC-01-00A0.dts#L61-L65
The main thing to take away from the PB-UART4-GNSS-5-CLICK.dts example is
the pps node..
https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/PB-UART4-GNSS-5-CLICK.dts#L46-L58
and the test it with the ppstest binary:
[ 30.902060] pps_core: LinuxPPS API ver. 1 registered
[ 30.907113] pps_core: Software ver. 5.3.6 - Copyright 2005-2007 Rodolfo
Giometti <[email protected]>
[ 30.945900] pps pps0: new PPS source pps.-1
[ 30.956911] pps pps0: Registered IRQ 74 as PPS source
debian@beaglebone:~$ sudo ppstest /dev/pps0
trying PPS source "/dev/pps0"
found PPS source "/dev/pps0"
ok, found 1 source(s), now start fetching data...
source 0 - assert 1523553378.571630304, sequence: 15 - clear 0.000000000,
