Subject: [PATCH v2 0/4] Devfreq cooling device
Date: Mon, 13 Jul 2015 18:33:54 +0100 [thread overview]
Message-ID: <1436808838-23391-1-git-send-email-javi.merino@arm.com> (raw)
This series introduces a devfreq cooling device in the thermal
framework. Devfreq is used for DVFS for devices other than the CPUs.
With a devfreq cooling device, the thermal framework can throttle them
to control temperature. The cooling device has the power extensions,
so it can be used by all governors in the thermal framework, including
the power allocator governor.
Changes since v1:
- Rename devfreq_qos_set_[max|min] to devfreq_set_[max|min] as
suggested by MyungJoo Ham
- Calculate devfreq load in the tracepoint so that it only happens
when the trace is enabled. Thanks Steven Rostedt.

PM / devfreq: cache the last call to get_dev_status()
devfreq_cooling: add trace information

PM / devfreq: Add function to set max/min frequency
thermal: Add devfreq cooling
