Sudeep,

I am not sure how it concerns me frankly :)

AFAICT, this is enabling fast switch based on some mechanism (internal
to scmi) and so either the cpufreq driver will have fast-switch
enabled or not, and both are fine by the cpufreq core.

And so I am confused on why my Ack is important here :)
