Did you try to reuse cpufreq-dt driver? It already handles most of this stuff, the only thing you need to do is to make sure clk_set_rate() for a CPU needs to handle all the clk stuff behind the scene. We haven't been accepting new implementations of the drivers which can work just fine with cpufreq-dt, please try to adapt to it. Thanks. -- viresh
