Merged in my local git repo (1/7 to 3/7 as those three are in /drivers/devfreq).
However, the admin requires me to setup the firewall again, so please wait
another day for the merged patches to show up in external network
(git.kernel.org) and to make a pull-request for Rafael.
(waiting firewall execption approvals from the admin)
Cheers,
MyungJoo

This patchset add new devfreq_event class to provide raw data to determine
current utilization of device which is used for devfreq governor.
The following description explains the feature of two kind of devfreq class:
- devfreq class (existing)
: devfreq consumer device use raw data from devfreq_event device for
determining proper current system state and change voltage/frequency
dynamically using various governors.
- devfreq_event class (new)
: Provide measured raw data to devfreq device for governor
