I'm trying to setup an LED indicator using the gpio pins on a Quartz64 model A. I've installed libgpiod, which comes with a number of tools, like gpiodetect and gpioinfo. With these tools, I can detect a five gpio chips (0-4). However, I don't think that any of these are linked to the main gpio pins since each of the chips has 32 lanes, but there are only 20 gpio pins on the Model A. Also, very few of the 5x32 lanes are named, and the few names are things like "fan" or "restart", not the names listed in section 3.8 of the wiki

This is an excellent tutorial on gpio programming, which originally led me to libgpiod
plebian.org/running/gpio/
However, all the examples are for the Model B. I'd hoped that the setup and naming convention for the Model A would be similarly easy, but it seems not. Does anyone have insight for the Model A?
For context, I've tried this while running armbian and gentoo, and the results are the same.
