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>; |
|
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>; |
|
};
