I have back ported your pcengines-apuv2 device and gpio-amd-fch GPIO 
driver to the kernel version 4.19 on OpenWrt.
If I compile and load this without the change no LEDs are visible in 
"/sys/class/leds"!

 From my point of view the connection between the GPIO and the LEDs 
subsystem is missing.
How should the LED subsystem know which GPIO to use?
If I add the change to the pcengines-apuv2 device then the LEDs will be 
visilbe under "/sys/class/leds"
and could be used, by OpenWrt userland.

Mybe I miss something.
