Hi,

Upcoming SCMI v3.2 specification (publicly available as BETA at [1])
introduces support to disable powercapping as a whole on the desired
zones.

This small series at first add the needed support to the core SCMI Powercap
protocol, exposing a couple more enable/disable protocol operations, and
then wires such new ops in the related Powercap framework helpers.

Based on v6.2-rc5.

Thanks,
Cristian
