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";
};
