+OMAP SoC HWRNG Module
+
+Required properties:
+
+- compatible : Should contain entries for this and backward compatible
+ RNG versions:
+ - "ti,omap2-rng" for OMAP2.
+ - "ti,omap4-rng" for OMAP4, OMAP5 and AM33XX.
+ Note that these two versions are incompatible.
+- ti,hwmods: Name of the hwmod associated with the RNG module
+- reg : Offset and length of the register set for the module
+- interrupts : the interrupt number for the RNG module.
+ Only used for "ti,omap4-rng".
+
+Example:
+/* AM335x */
+rng: rng@48310000 {
+ compatible = "ti,omap4-rng";
+ ti,hwmods = "rng";
+ reg = <0x48310000 0x2000>;
