Keystone SoC Hardware Random Number Generator(HWRNG) Module
|
|
|
|
On Keystone SoCs HWRNG module is a submodule of the Security Accelerator.
|
|
|
|
- compatible: should be "ti,keystone-rng"
|
|
- ti,syscon-sa-cfg: phandle to syscon node of the SA configuration registers.
|
|
This registers are shared between hwrng and crypto drivers.
|
|
- clocks: phandle to the reference clocks for the subsystem
|
|
- clock-names: functional clock name. Should be set to "fck"
|
|
- reg: HWRNG module register space
|
|
|
|
Example:
|
|
/* K2HK */
|
|
|
|
rng@24000 {
|
|
compatible = "ti,keystone-rng";
|
|
ti,syscon-sa-cfg = <&sa_config>;
|
|
clocks = <&clksa>;
|
|
clock-names = "fck";
|
|
reg = <0x24000 0x1000>;
|
|
};
