Property "fsl,wdt-continue-in-low-power" allows the watchdog to continue
running in low power modes (STOP and DOZE). By default, the watchdog is
suspended in these modes. This property provides the option to keep the
watchdog active during low power states when needed.
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).
