     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>;
    };
