Better to ask for fixing it, instead of giving conditional review tag, IMHO. Best regards, Krzysztof

IPQ6018 comes in multiple SKU-s and some of them dont support all of the OPP-s that are current set, so lets utilize CPUFreq NVMEM to allow only supported OPP-s based on the SoC dynamically. As an example, IPQ6018 is generaly rated at 1.8GHz but some silicon only goes up to 1.5GHz and is marked as such via an eFuse.
