+Qualcomm MSM pseudo random number generator.
+
+Required properties:
+
+- compatible : should be "qcom,prng"
+- reg : specifies base physical address and size of the registers map
+- clocks : phandle to clock-controller plus clock-specifier pair
+- clock-names : "core" clocks all registers, FIFO and circuits in PRNG IP block
+
+Example:
+
+ rng@f9bff000 {
+ compatible = "qcom,prng";
+ reg = <0xf9bff000 0x200>;
+ clocks = <&clock GCC_PRNG_AHB_CLK>;
+ clock-names = "core";
+ };
