Changes since v1:
1. Indent example with four spaces (more readable),
2. Remove unneeded timeout-sec description and include generic bindings.

-
-The Samsung's Watchdog controller is used for resuming system operation

-
-Required properties:
-- compatible : should be one among the following
-	- "samsung,s3c2410-wdt" for S3C2410
-	- "samsung,s3c6410-wdt" for S3C6410, S5PV210 and Exynos4

-	- "samsung,exynos5420-wdt" for Exynos5420
-	- "samsung,exynos7-wdt" for Exynos7
-
-- reg : base physical address of the controller and length of memory mapped
-	region.
-- interrupts : interrupt number to the cpu.
-- samsung,syscon-phandle : reference to syscon node (This property required only
-	in case of compatible being "samsung,exynos5250-wdt" or "samsung,exynos5420-wdt".
-	In case of Exynos5250 and 5420 this property points to syscon node holding the PMU
-	base address)
-
-Optional properties:
-- timeout-sec : contains the watchdog timeout in seconds.

-Example:
-
