-* 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
-
-Optional properties:
-- big-endian: If present the watchdog device's registers are implemented
- in big endian mode, otherwise in native mode(same with CPU), for more
- detail please see: Documentation/devicetree/bindings/regmap/regmap.txt.
-- fsl,ext-reset-output: If present the watchdog device is configured to
- assert its external reset (WDOG_B) instead of issuing a software reset.
-- timeout-sec : Contains the watchdog timeout in seconds

-Examples:
-
-wdt@73f98000 {
- compatible = "fsl,imx51-wdt", "fsl,imx21-wdt";
- reg = <0x73f98000 0x4000>;
