This is to use cpufreq dt driver target_intermediate to implement cpufreq for i.MX7ULP, because i.MX7ULP has some specific requirements for core clk changing. To make cpufreq on i.MX7ULP full function, there still more patches required: https://patchwork.kernel.org/cover/11491149/ https://patchwork.kernel.org/patch/11390559/ However with this current patchset applied, it not break anything, because the cpufreq device has not been registered, and opp table not added.
