-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 */
