It appears that after commit to the gpio-dwapb driver the quirk for Intel Galileo Gen 2 stopped working. I tried a few approaches but none of them worked besides the fact that they copy like a ~10% of the gpiolib-acpi functionality. Instead I decided to come back to a mix of v1 [1] of the initial series (the v3 has been applied) and Mika's suggestion about using gpio_to_desc() API. Unfortunately it requires to have a quirk in the core, but in comparison to v1 it much less intrusive and doesn't use any predefined numbers. I would like to create an immutable branch and send TWIMC (GPIO and ACPI subsystems I guess). This is material for v5.12-rcX.
