There are upstream comments suggesting that we reference the same shared OPP table from all the BWMONs that share the same OPP table. However, there will be some DTBS CHECK warnings[2] if we do reference the same shared OPP table. Therefore, I pushed this patch series to collect some comments on whether we can have separate OPP tables for each BWMON, as the OPP table of "pmu@90b5400" and "pmu@90b6400" in this patch series.

Thank you for the explanation.

I mistakenly thought that certain information should not be included in the cover letter.
