RE: ACPI binding with SCMI

[Pawandeep Oza]

I am looking for scmi binding to ACPI. Basically, SCMI based perf control. 
We have ACPI based system, so I am looking for where I can describe (some way to describe doorbell and share memory in ACPI), 
and then scmi perf can bind to it via some sort of transport (perhaps fastchannels ? )

Regards,
Oza.

They simply don't bind to PCC, PCC can't be fast channel. What exactly are you looking for here ? If you provide more details on that, I can see if I can help or suggest or may be explore along with you if the solution doesn't exists yet.
