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";
};
