Wow! Can we see ACPI tables for these boards? Care to share (via some
file share service) output of `acpidump -o tables.dat` ?

Please find acpidump [1]. FYI I'm PC Engines firmware maintainer
(firmware is coreboot based), so I can fix required things. I'm pretty
sure that ACPI tables are not in best shape.


Thanks for the dump,

By the way I have seen that the driver
https://github.com/torvalds/linux/blob/master/drivers/gpio/gpio-amdpt.c
is using the acpi to get the mmio address. I think this is the way to go
to get the acpi mmio address in the gpio-apu driver as well.

What is the right "acpi_device_id" for the APU3?
