Hi all,

The Energy Model (EM) supports power values expressed in an abstract scale
via new API. The SCMI performance protocol provides the information about
power scale. This patch set implements the needed interface and updates
cpufreq driver to set the right scale in the EM.

It is based on top of patch series adding milli-Watts flag in EM [1]
(next-20201124 was used as a base).

Regards,
Lukasz
