Not only in those subsystem, but any IRQ numbering change (for example, async driver probe, IRQ numbering scheme globally, etc) may break this. It's definitely a bug in firmware.

The kernel PNP acpi driver now supports GpioInt.

The corresponding change in coreboot (which uses GpioInt instead of hardcoded irq number)

  https://chromium.googlesource.com/chromiumos/third_party/kernel/+/9104bd79ad00f9bfc7d14476dce6ac6058519883

commit 9104bd79ad00f9bfc7d14476dce6ac6058519883

FROMLIST: PNP / ACPI: add support for GpioInt resource type

The PNP ACPI driver parses ACPI interrupt resource but not
GpioInt resource. When the firmware passes GpioInt resource
for IRQ the PNP ACPI driver ignores it and hence the interrupt for
the particular driver will not work.
One such example is 8042 keyboard which uses PNP driver for obtaining
the interrupt resource. On Intel Braswell project GpioInt is used
instead of interrupt resource and the keyboard driver fails to
register interrupt.
Fix the issue by parsing GpioInt resource type.

Reks: do not hardcode virtual interrupt numbers

Instead of hardcoding virtual interrupt numbers that may change as
the kernel changes, use GpioInt() reosurces to describe keyboard
and touchscreen interrupt lines.

FROMLIST: PNP / ACPI: add support for GpioInt resource type

The PNP ACPI driver parses ACPI interrupt resource but not
GpioInt resource. When the firmware passes GpioInt resource
for IRQ the PNP ACPI driver ignores it and hence the interrupt for
the particular driver will not work.
One such example is 8042 keyboard which uses PNP driver for obtaining
the interrupt resource. On Intel Braswell project GpioInt is used
instead of interrupt resource and the keyboard driver fails to
register interrupt.
Fix the issue by parsing GpioInt resource type.
