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";

	};
