-* 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
-occurred.
-
-Required properties:
-- compatible : should be one among the following
-	- "samsung,s3c2410-wdt" for S3C2410
-	- "samsung,s3c6410-wdt" for S3C6410, S5PV210 and Exynos4
-	- "samsung,exynos5250-wdt" for Exynos5250
-	- "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:
-
-watchdog@101d0000 {
-	compatible = "samsung,exynos5250-wdt";
-	reg = <0x101D0000 0x100>;
-	interrupts = <0 42 0>;
-	clocks = <&clock 336>;
-	clock-names = "watchdog";
-	samsung,syscon-phandle = <&pmu_syscon>;
-};

[PATCH 2/2] dt-bindings: watchdog: Add missing clocks requirement in Samsung SoC watchdog

[Krzysztof Kozlowski]

The Samsung SoC watchdog driver always required providing a clock
(either through platform data or from DT).  However when bindings were
added in commit 9487a9cc7140 ("watchdog: s3c2410: Add support for device
tree based probe"), they missed the requirement of clock.

We need a common schema for this and the node name.

Also note that anything with a unit suffix already has a type 
definition, so we don't really need to define it again.

Common schema in dt-schema or in Linux kernel bindings? If the latter,
I can add it.
