Interesting. I agree that doing a DT binding for these will be trivial,
and the implementation in Linux should also be straightforward, thanks
for pointing these out.
However, it seems that the implementation that qemu uses is incompatible
with ARM64, since GPE is not part of the ACPI hardware reduced mode.
