* 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.
