-Exynos True Random Number Generator

-Required properties:
-
-- compatible  : Should be "samsung,exynos5250-trng".
-- 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@...30600 {
-		compatible = "samsung,exynos5250-trng";
-		reg = <0x10830600 0x100>;
-		clocks = <&clock CLK_SSS>;
-		clock-names = "secss";
