Kernel-4.18.0-80.el8_ks-sa-rng

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>;
};
