- atmel,disable : Should be present if you want to disable the watchdog.

- atmel,idle-halt : Should be present if you want to stop the watchdog when

	entering idle state.

	CAUTION: This property should be used with care, it actually makes the

	watchdog not counting when the CPU is in idle state, therefore the

	watchdog reset time depends on mean CPU usage and will not reset at all

	if the CPU stop working while it is in idle state, which is probably

	not what you want.

- atmel,dbg-halt : Should be present if you want to stop the watchdog when

	entering debug state.
