Hi Dmitry, The v5.10-rc6 was released from linus git tree. Generally, I will send the pull-quest about devfreq to linux-pm.git maintainer after releasing the v5.1-rc7 for the integration test on linux-pm.git. The icc patches in this patch have not yet merged. If these patches are not merged before v5.10-rc7, Maybe, I'll apply the devfreq patches for v5.12-rc1.
