Thanks a lot for your advice, now things are clearer.
My idea is as follows:
1. Add all frequencies supported by SoCs in ipq6018.dtsi
2. Move cpu-supply and mp5496 nodes to ipq6018-mp5496.dtsi
&CPU0 {
cpu-supply = <&ipq6018_s2>;
};
...
&rpm_requests {
regulators {
rpm-mp5496...
ipq6018_s2...
};
};

Thank you but no need. The CPUFreq NVMEM driver will give the CPU
maximum frequency based on the cpu_speed_bin and opp-supported-hw.
Thanks,
