Subject:
 [RFC][PATCH v021 2/9] cpufreq: intel_pstate: Drop Arrow Lake from "scaling
 factor" list

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Since HYBRID_SCALING_FACTOR_MTL is not going to be suitable for Arrow
Lake in general, drop it from the "hybrid scaling factor" list of
platforms, so the scaling factor for it will be determined with the
help of information provided by the platform firmware via CPPC.
