-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@10830600 {
- compatible = "samsung,exynos5250-trng";
- reg = <0x10830600 0x100>;
- clocks = <&clock CLK_SSS>;
- clock-names = "secss";
- };
