Glad you asked :)

Heh, I'm not sure I'm so glad. Did I mention I hate ACPI? Perhaps it's still not too late for me just to define a DT binding and use PRP0001 for it :)

Long story short, QEMUVGID is indeed out of spec, but it works
both because of guest compatibility with ACPI 1.0, and because no one
much uses it.

I think it's reasonable enough to follow that example and use AMZNVCLK (or QEMUVCLK, but there seems little point in both) then?

I'd stick to spec. If you like puns, QEMUC10C maybe?
