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
/* AM335x */
