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 ?
