A general comment when you do this kind of work:

Do not write a single patch that impacts at least three different
subsystems. As it is, it is unmergeable.

Now the real question is *WHY* we need this kind of monstruosity?
ACPI deals with PCI, not with exotic busses and whatnot. If you want
to be creative, DT is your space. ACPI is designed to be plain and
boring, and that's how we like it.

Thanks,

         M.
