Hi all,

This patch set v2 aims to refactor the thermal pressure update
code. There are already two clients which do similar thing:
convert the capped frequency value into the capacity of
affected CPU and call the 'set' function to store the
reduced capacity into the per-cpu variable.
There might be more than two of these users. In near future
it will be scmi-cpufreq driver, which receives notification
from FW about reduced frequency due to thermal. Other vendors
might follow. Let's avoid code duplication and potential
conversion bugs. Move the conversion code into the arch_topology.c
where the capacity calculation setup code and thermal pressure sit.

Apart from that $subject patches, there is one patch (3/5) which fixes
issue in qcom-cpufreq-hw.c when the thermal pressure is not
updated for offline CPUs. It's similar fix that has been merged
recently for cpufreq_cooling.c:
2ad8ccc17d1e4270cf65a3f2

Changes:
v2:
- added Reviewed-by from Thara for patch 3/5
- changed the doxygen comment and used mult_frac()
   according to Thara's suggestion in patch 1/5
v1 -> [1]


Gentle ping.

Viresh, Daniel, Rafael could you have a look at this, please?

Regards,
Lukasz
