They all do it in the same redundant way. It would be better if we can get rid of redundancy by initializing CPU OPPs from CPU core code for all CPUs (that have a "operating-points" property defined in their node). This patchset callsl of_init_opp_table() directly from register_cpu() right after CPU device is registered. Later patches updates existing cpufreq drivers which were calling of_init_opp_table() directly. V3->V4: - Remove of_init_cpu_opp_table() and use of_init_opp_table() instead after adding more print messages to it. - Drop a rather unrelated patch which was getting rid of dependency on thermal for cpufreq-cpu0. Will be sent separately.
