cpufreq: add support for CPU DVFS based on SCMI message protocol
On some ARM based systems, a separate Cortex-M based System Control Processor(SCP) provides the overall power, clock, reset and system control including CPU DVFS. SCMI Message Protocol is used to communicate with the SCP. This patch adds a cpufreq driver for such systems using SCMI interface to drive CPU DVFS. Cc: linux-pm@vger.kernel.org Acked-by: Rafael J.
