Ref: function: cpufreq_passive_register_notifier() https://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux.git/commit/?h=devfreq-testing&id=b670978ddc43eb0c60735c3af6e4a370603ab673 After I discuss with Angelo and Jia-wei, we think we are keeping the function in target_index and if the cci is not ready we will use the voltage which is set by bootloader to prevent high freqeuncy low voltage crash. And then we can keep seting the target frequency. We assume the setting of bootloader is correct and we can do this. For the SoCs that including ci hardware (8183 and 8186), we think it's not ok if we don't probe cci correctly. If we failed to get cci node, I think we sould return -ENODEV and the probe of cpufreq failed. What do you think the solution? BRs, Rex
