APM X-Gene SoC random number generator.
Required properties:
- compatible : should be "apm,xgene-rng"
- reg : specifies base physical address and size of the registers map
- clocks : phandle to clock-controller plus clock-specifier pair
- interrupts : specify the fault interrupt for the RNG device
Example:
rng: rng@10520000 {
compatible = "apm,xgene-rng";
reg = <0x0 0x10520000 0x0 0x100>;
interrupts = <0x0 0x41 0x4>;
clocks = <&rngpkaclk 0>;
};
