I meant first one. using "qcom,rng-ee".

Then please provide some reasons.

New IP block available on SM8450 and newer platform is true random 
number generator with it's entropy source. Also it is NIST SP800 90B 
compliant.
By introducing "qcom,rng-ee" I am also planning to add hwrng support in 
driver.

I am looking for generic compatible string for all SoCs for which core
clock can be optional, same as we have "qcom,prng-ee".

There is a generic compatible already... but anyway, is the clock really
optional? Or just configured by firmware?

Clock is configured using security firmware.

If we are using SoC name in compatible string, for each SoC support we
need to update qcom,prng.yaml file.

So you were talking about second case from my email? Still not sure what
you want to propose, but just in case - please always follow DT bindings
guidelines:
