please split into two patches (operating points + cpu-supply)
and use the operating-points-v2 binding.

You use operating-points-v2 or the V1 bindings for this SoC? The SoCs using
operating-points-v2 don't need such changes anymore.

Yes, I use operating-points-v2.

Did you check with current mainline? It should work without this patches.
