Usually we do not recommend hiding code behind !CONFIG_OF because this
limits possible usage on ACPI systems via PRP0001. Not sure if it is
applicable here, because there is already ACPI matching.

I would suggest choose whatever makes code simpler... Or just mark some
pieces with __maybe_unused if they are really not used? That would avoid
ifdeffery.


Best regards,
Krzysztof
