Hi all,
This patch set introduces support for devices in the Energy Model (EM) framework. It will unify the power model for thermal subsystem and make it simpler. The 1st patch refactors EM framework and adds support for devices. The 2nd patch changes dev_pm_opp_of_register_em() in OPP/OF which now should take as an argument struct device pointer. It touches a few trees (OMAP, NXP, mediatek) updating their CPUfreq drivers to the new interface. Patch 3 changes thermal devfreq cooling removing old code for calculating local power table. It simplifies the code and uses EM for requested power calculation. Last patch 4 is based on 'drm-misc-next' and adds EM to Panfrost driver.
The patch set is based on v5.5-rc6 tag (excluding last patch).
Regards, Lukasz Luba
