+Exynos Pseudo Random Number Generator
+
+Required properties:
+
+- compatible : Should be "samsung,exynos4-rng".
+- reg : Specifies base physical address and size of the registers map.
+- clocks : Phandle to clock-controller plus clock-specifier pair.
+- clock-names : "secss" as a clock name.
+
+Example:
+
+ rng@10830400 {
+ compatible = "samsung,exynos4-rng";
+ reg = <0x10830400 0x200>;
+ clocks = <&clock CLK_SSS>;
+ clock-names = "secss";
+ };
