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
|
|
|
|
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>;
|
|
};
