I'm not sure about the enable-once flag, which seems to just map to the "nowayout" watchdog option that is not a hardware feature at all and should probably be kept as a software setting only, rather than settable through DT. If it is kept, it should have a standard name and get turned into a boolean (present/absent) property rather than a 0/1 integer property. The interval should really be specified in terms of seconds or miliseconds, not in clock cycles.
