Hi Andrew
I saw AppliedMicro(apm) xgene has used "phy-handle" for ACPI method, so
I guess "phy-handle" has become part of the ACPI standard. But I cannot
make sure.
I tried to confirm the property is defined in the document(Like DT
binding). However, I did not find any documentation on the description
property definition on the UEFI/ACPICA website.
But when I was reading Documentation/acpi/DSD-properties-rules.txt, my
understanding is we should try to conform to DT bindings. So maybe ACPI
doesn't have such a document, just DT bindings.
Cheers,
Dongsheng
