-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>;

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?
