Thanks Rob. Just a quick question, who is going to merge this seeing it 
is a standalone dt binding conversion to yaml?

Ping on this, it appears to have gone stale.

Who is going to pick this up?

-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 {
