[PATCH 7/8] cpufreq: scpi: Use auto-registration for energy model
From: Viresh Kumar <viresh.kumar@linaro.org>
Date: 2021-08-10 07:37:34
Also in:
linux-pm, lkml
Subsystem:
cpu frequency scaling framework, system control & power/management interface (scpi/scmi) message protocol drivers, the rest · Maintainers:
"Rafael J. Wysocki", Viresh Kumar, Sudeep Holla, Linus Torvalds
Use the CPUFREQ_REGISTER_WITH_EM flag to allow cpufreq core to automatically register with the energy model. This allows removal of boiler plate code from the driver and fixes the unregistration part as well.
