-Qualcomm MSM pseudo random number generator.
-
-Required properties:
-
-- compatible  : should be "qcom,prng" for 8916 etc
-              : should be "qcom,prng-ee" for 8996 and later using EE
-		(Execution Environment) slice of 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";
-	};
