Keystone SoC Hardware Random Number Generator(HWRNG) Module

On Keystone SoCs HWRNG module is a submodule of the Security Accelerator.

- compatible: should be "ti,keystone-rng"
- ti,syscon-sa-cfg: phandle to syscon node of the SA configuration registers.
		    This registers are shared between hwrng and crypto drivers.
- clocks: phandle to the reference clocks for the subsystem
- clock-names: functional clock name. Should be set to "fck"
- reg: HWRNG module register space

Example:
/* K2HK */

rng@24000 {
	compatible = "ti,keystone-rng";
	ti,syscon-sa-cfg = <&sa_config>;
	clocks = <&clksa>;
	clock-names = "fck";
	reg = <0x24000 0x1000>;
};
