From 2d41dc23804d075e248ff01d16d9d424bcbc1180 Mon Sep 17 00:00:00 2001 From: Pierre Gondois <Pierre.Gondois@arm.com> Date: Wed, 18 May 2022 11:09:01 +0200 Subject: [PATCH] cpufreq: CPPC: Enable dvfs_possible_from_any_cpu The communication mean of the _CPC desired performance can be PCC, System Memory, System IO, or Functional Fixed Hardware (FFH). PCC, SystemMemory and SystemIo address spaces are available from any CPU. Thus, dvfs_possible_from_any_cpu should be enabled in such case. For FFH, let the FFH implementation do smp_call_function_*() calls.
