Changes since v2:
1. Add additionalProperties false,
2. Include clock header and use defines instead of clock numbers.

Changes since v1:
1. Indent example with four spaces (more readable).

-Exynos Pseudo Random Number Generator

-Required properties:
-
-- compatible : One of:
- - "samsung,exynos4-rng" for Exynos4210 and Exynos4412
- - "samsung,exynos5250-prng" for Exynos5250+
-- 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";
- };
