-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 at 10520000 {
- compatible = "apm,xgene-rng";
- reg = <0x0 0x10520000 0x0 0x100>;
- interrupts = <0x0 0x41 0x4>;
- clocks = <&rngpkaclk 0>;
- };
