I will soon send a support patch against ACPI GPIO library code.

If you don't mind, let me write this patch(set) instead:)

I leave to you whatever AMD code. It will suit our both interests :-)

Excellent! Thank you!

I feel itchy
to fix this touchpad issue by myself after spending about a month of
my internship at Linux Foundation investigating this touchpad issue.
There are many enthusiastic Linux users waiting to get their touchpads
fixed and I could prioritize this task since I don't have other
obligations. I have provided a fallback solution [1] to save their
touchpads but it seems patches on gpiolib-acpi.c and pinctrl-amd could
reach mainline kernel much earlier.
