The _DSD-method for "PRP0001"-devices in ACPI allows to use Devicetree properties inside ACPI, especially it allows to re-use Devicetree's "compatible"-property. But this is for a different use case (using Devicetree properties inside ACPI, not add ACPI properties in Devicetree).
Before we are going further with this here is a BIG CAVEAT.
PRP0001 MUST NOT be used in production devices.
This has been derived solely for debugging / pre-production testing / etc purposes. The real devices must have an official ACPI _HID.
