We need to add compatible for H616 to H6 cpufreq driver bindings.

Please describe the hardware, not what is needed for drivers.
Got it. Sorry.


Also enable opp_supported_hw property that will be needed for H616.

Why? It is already allowed. You should rather explain the values.
Yea this can be dropped. I forgot to remove it. My bad.
Also the values i think are very clear ? The values converted to binary represent which chip revision is allowed to use the specified frequency.
1 bit for each revision.
