* Freescale i.MX Watchdog Timer (WDT) Controller



Required properties:

- compatible : Should be "fsl,<soc>-wdt"

- reg : Should contain WDT registers location and length

- interrupts : Should contain WDT interrupt



Examples:



wdt@73f98000 {

	compatible = "fsl,imx51-wdt", "fsl,imx21-wdt";

	reg = <0x73f98000 0x4000>;

	interrupts = <58>;
