Subject: [PATCH 0/3] devfreq: Add support for devices which can idle
Date: Mon,  3 Sep 2012 19:59:35 +0530	[thread overview]
Message-ID: <1346682578-24312-1-git-send-email-rajagopal.venkat@linaro.org> (raw)

This patchset updates devfreq core to add support for devices
which can idle. When device idleness is detected perhaps
through runtime-pm, need some mechanism to suspend devfreq
load monitoring and resume when device is back online.

patch 1 introduce core design changes - per device work, decouple
delayed work from core and event based interaction.
patch 2 add devfreq suspend and resume apis.
patch 3 current frequency bug fix and add new sysfs attribute for
governor predicted next target frequency.

The existing devfreq apis are kept intact. Two new apis
devfreq_suspend_device() and devfreq_resume_device() are
added to support suspend/resume of device devfreq.
