Hi, Dmitry > How is it "some"? You are enabling this opp for all IPQ6000 SoC instances. This is not the case, please see `opp-supported-hw = <0x4>;`. Also: https://github.com/torvalds/linux/blob/master/drivers/cpufreq/qcom-cpufreq-nvmem.c#L345 This 1.2GHz Frequency only takes effect when BIT(2) exists. For fused 1.5GHz devices, the 1.2GHz frequency will not appear. I have tested this patch on both fused 1.2GHz and 1.5GHz devices. Thanks, Chukun -- 2.25.1
