Hello,
This patch series adds support for cpufreq on H616 SoC.
H616 is bit interesting. It has SoC versions that have different
frequencies and uV but some versions have the same version ID and
we have to check the SoC revision to differentiate between them.
This is done via SMCCC. Thus the exporting of the symbol.
Please note that this series depends on my THS series which
depends on my SID series.
I also have not enabled the cpufreq on any devices to minimize
the series dependencies and I did test it only on CB1 where
it works.
Cheers,
Martin
