This series is a follow up for the patches which got merged to v5.9-rc1. It aims to change the thermal devfreq cooling and use the Energy Model instead of private calculation and structures. The new registration interface in the patch 3/5 helps to register devfreq cooling and the EM in one call. There is also another improvement, patch 2/5 is changing the way how thermal gets the device status. Now it's taken on demand and stored as a copy. The last patch wouldn't go through thermal tree, but it's here to consistency. The patch set is based on current next (next-20200921).
