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?
