* 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.
