* Samsung's Watchdog Timer Controller



The Samsung's Watchdog controller is used for resuming system operation

after a preset amount of time during which the WDT reset event has not

occured.



Required properties:

- compatible : should be "samsung,s3c2410-wdt"

- reg : base physical address of the controller and length of memory mapped

	region.

- interrupts : interrupt number to the cpu.
