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";
};
