I omitted the OPP definitions to avoid cluttering the example. I'm happy to add them if DT folks also think it would add value. > 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 ? cpu0_opp03 and the other phandles are specific OPP entries, that indicate the throttler which frequencies/OPPs should be used for throttling. For devices/CPUs with multiple levels of throttling multiple entries from its OPP set are listed. In the example a single level of throttling is used for all devices/CPUs.
