Hi all,

This patch set introduces support for devices in the Energy Model (EM)
framework. It will unify the power model for thermal subsystem. It will
make simpler to add support for new devices willing to use more
advanced features (like Intelligent Power Allocation). Now it should
require less knowledge and effort for driver developer to add e.g.
GPU driver with simple energy model. A more sophisticated energy model
in the thermal framework is also possible, driver needs to provide
a dedicated callback function. More information can be found in the
updated documentation file.

First 7 patches are refactoring Energy Model framework to add support
of other devices that CPUs. They change:
- naming convention from 'capacity' to 'performance' state,
- API arguments adding device pointer and not rely only on cpumask,
- change naming when 'cpu' was used, now it's a 'device'
- internal structure to maintain registered devices
- update users to the new API
Patch 8 updates OPP framework helper function to be more generic, not
CPU specific.
Patches 9-14 change devfreq cooling, dropping part of old power model and
adding registration with Energy Model via exported GPL function.
The last path is a simple change for Panfrost GPU driver.

The patch set is based on linux-next tag next-20200508.

Do you think it is possible to respin against linux-pm next ?

Yes, I will do it and send the v8.


I wanted to try the series but I'm getting non trivial conflicts with
the devfreq_cooling changes



Let me take care of this.

Regards,
Lukasz
