* 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
