This is primarily used by a device that uses ACPI and the driver uses the firmware-agnostic APIs to get at this. However, it also means that the driver effectively provides this same support for DT via those APIs and therefore it makes sense to document that part even if there are no current users of the DT bits. One big advantage of this is that it helps keep the ACPI and DT bindings in sync, and document this on the DT side also allows us to document the ACPI side of things where no formal documentation exists, as far as I know.
