-* 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>;
-};
