     OMAP SoC and Inside-Secure HWRNG Module
     
     Required properties:
     
     - compatible : Should contain entries for this and backward compatible
       RNG versions:
       - "ti,omap2-rng" for OMAP2.
       - "ti,omap4-rng" for OMAP4, OMAP5 and AM33XX.
       - "inside-secure,safexcel-eip76" for SoCs with EIP76 IP block
      Note that these two versions are incompatible.
    - ti,hwmods: Name of the hwmod associated with the RNG module
    - reg : Offset and length of the register set for the module
    - interrupts : the interrupt number for the RNG module.
                    Used for "ti,omap4-rng" and "inside-secure,safexcel-eip76"
    - clocks: the trng clock source. Only mandatory for the
      "inside-secure,safexcel-eip76" compatible, the second clock is
      needed for the Armada 7K/8K SoCs
    - clock-names: mandatory if there is a second clock, in this case the
      name must be "core" for the first clock and "reg" for the second
      one
    
    
    Example:
    /* AM335x */
    rng: rng@48310000 {
            compatible = "ti,omap4-rng";
            ti,hwmods = "rng";
            reg = <0x48310000 0x2000>;
            interrupts = <111>;
    };
    
    /* SafeXcel IP-76 */
    trng: rng@f2760000 {
            compatible = "inside-secure,safexcel-eip76";
            reg = <0xf2760000 0x7d>;
            interrupts = <GIC_SPI 59 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&cpm_syscon0 1 25>;
    };
