If possible, I hope the more detailed example for "cpu0_opp03, &cpu1_opp02, &gpu_opp03" because I'm confusing the meaning of 'cpu0_opp03' phandle. cpu0_opp03 indicates the only one specific OPP entry among set of OPP entries of CPU0 cpufreq? or cpu0_opp03 indicates the set of OPP entries for CPU0 cpufreq ? -- Best Regards, Chanwoo Choi Samsung Electronics
