Hello, I am currently trying to use a GPS for an accurate Network Time Protocol.
The router I am using is a Turris Omnia 2020(https://www.turris.com/en/omnia/overview/) and the gps is a sintrones VDB-810DR(https://www.sintrones.com/VDB-810DR.html).
I managed to conect the gps through usb and got it working. I also connected the PPS from the GPS to the GPIO44(MPP44) pin on the board, but I don't know how I should configure the GPIO pin in the device tree. The goal is to get the kmod-pps-gpio driver working.
I am building onto the openwrt open-source code.
