I looked at the patch 5/5. It shows two clusters, e and p, with four CPUs in each cluster. And as per the OPP table all the CPUs in cluster e are part of same frequency domain, i.e. switch rate together. Same with all CPUs of cluster p.
And I also see both the clusters have separate OPP tables.

Can you show how the DT looks in this case ? I am still not clear on what the scenario is here :(
