+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";
+ };

+HWRNG support for the n2_rng driver
+
+Required properties:
+- reg : base address to sample from
+- compatible : should contain one of the following
+ RNG versions:
+ - 'SUNW,n2-rng' for Niagara 2 Platform (SUN UltraSPARC T2 CPU)
+ - 'SUNW,vf-rng' for Victoria Falls Platform (SUN UltraSPARC T2 Plus CPU)
+ - 'SUNW,kt-rng' for Rainbow/Yosemite Falls Platform (SUN SPARC T3/T4), (UltraSPARC KT/Niagara 3 - development names)
+ more recent systems (after Oracle acquisition of SUN)
+ - 'ORCL,m4-rng' for SPARC T5/M5
+ - 'ORCL,m7-rng' for SPARC T7/M7
+
+Examples:
+/* linux LDOM on SPARC T5-2 */
+Node 0xf029a4f4
+ .node: f029a4f4
+ rng-#units: 00000002
+ compatible: 'ORCL,m4-rng'
+ reg: 0000000e
+ name: 'random-number-generator'
