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).

Lukasz

More scmi stuff came in which I had to apply and so I applied this to
the ARM tree.

Rafael: I had to rebase this over one of the patches from your tree,
which was based on rc3:

commit c250d50fe2ce ("PM: EM: Add a flag indicating units of power values in Energy Model")

I hope you won't rebase it any further.

Applied. Thanks.


Thank you Viresh!
