Can you figure out what pin number it is trying to use?
Thanks,
Mark
P.S. Feel free to finish the driver yourself if you have time. This
sort of thing is way easier if you have the hardware. The
hardware itself should be very similar to aplgpio(4). It's just
that the registers moved around a bit and there is a single ACPI
device for all the pin "communities" instead of the model of
separate ACPI devices for each community that aplgpio(4) uses.
