Hi There...
Thanks for the help, it means a lot...
Regarding item 4:
It appears to be already installed (not sure if I did this in my fumbling
around or if it came in with something else), so I'll look forward to your
upcoming driver....Alan

It might be automatic, the modules should be built for any "uspace" config:

If you install "gpiod" does "gpioinfo" work?
If so, then I am currently working on a driver that uses libgpiod.
That might work for you (though not at the moment)
