Mike is working on a new CCF feature called "coordinated clock rate changes"
which would help to migrate mt8173-cpufreq driver to generic cpufreq-dt
driver, and I am working with him to port MT8173 clock driver on the new
feature. So I think that's why this patch was not picked since it will
be migrated to new implementation once the new feature's ready.
Are you plannig to post those patches on the mailing list ?
Or is it fine for you to take this first and then I will refine it for
the new feature later?
