gpiolib on orange pi 5?

Has anyone found a working gpiolib implementation for Armbian on Orange  Pi 5?

 

I'm aware of wiringPi and it sort of works. However, being able to use the "real stuff" so to speak would make my life easier.

hm... After some digging, it seems like one main problem,  perhaps the only one, is the lack of gpio line naming. gpiolib is centered around the idea that lines are referenced using names rather than numbers. However, when listing the names they are all empty i. e. "". This makes it impossible to reference any line.

 

This is obviously about boot/dtb. Moreover, while orangepi 5 successfully reuses the rockchip stuff, the actual names are board specific. 

 

I have never worked with the dtb/dts stuff. But assigning names to the connections should not be that complicated.  Actually, names like "gpio0", "gpio1" etc reflecting physical lines should  be fine.

 

Any hint out there where to start?

Quite a while ago I added GPIO names to the rock-3a. Perhaps you can get an idea how to do this.
