Subject[PATCH 0/4] PM / devfreq: add possibility for delayed work
Date
Add possibility for changing work from deferred to delayed in devfreq
workqueue. This can be done with

echo 1 > /sys/class/devfreq/devfreqX/delayed_timer

Second way is to use config option, in that case delayed timer will be
used from devfreq start.

Default behaviour is to stick with old delayed timer.

This patchset was inspired by Lukasz Luba patches and discussion that
follows, see
