   1 OMAP SoC and Inside-Secure HWRNG Module
   2
   3 Required properties:
   4
   5 - compatible : Should contain entries for this and backward compatible
   6   RNG versions:
   7   - "ti,omap2-rng" for OMAP2.
   8   - "ti,omap4-rng" for OMAP4, OMAP5 and AM33XX.
   9   - "inside-secure,safexcel-eip76" for SoCs with EIP76 IP block
  10   Note that these two versions are incompatible.
  11 - ti,hwmods: Name of the hwmod associated with the RNG module
  12 - reg : Offset and length of the register set for the module
  13 - interrupts : the interrupt number for the RNG module.
  14                 Used for "ti,omap4-rng" and "inside-secure,safexcel-eip76"
  15 - clocks: the trng clock source
  16
  17 Example:
  18 /* AM335x */
  19 rng: rng@48310000 {
  20         compatible = "ti,omap4-rng";
  21         ti,hwmods = "rng";
  22         reg = <0x48310000 0x2000>;
  23         interrupts = <111>;
  24 };
  25
  26 /* SafeXcel IP-76 */
  27 trng: rng@f2760000 {
  28         compatible = "inside-secure,safexcel-eip76";
  29         reg = <0xf2760000 0x7d>;
  30         interrupts = <GIC_SPI 59 IRQ_TYPE_LEVEL_HIGH>;
  31         clocks = <&cpm_syscon0 1 25>;
  32 };
