And why exactly would that be a DT property? If system is sleeping
(assuming this is what you meant by low power), no one will pet the dog,
thus watchdog makes no sense.

Otherwise I fail to see how this is a hardware property and we do not
accept SW properties (see writing bindings, numerous presentations).
