RE: [RFC] PM / devfreq: Add support for alerts

Currently, DEVFREQ reevaluates the device state periodically and/or
based on the OPP list changes. Private API has to be exposed to allow
the device driver to alert/notify the governor to reevaluate when a new
set of data is available. This makes the governor more coupled to a
particular device driver. We can improve here by exposing a DEVFREQ API
to allow the device drivers to send generic alerts to the governor.

Hello Akhil,

It appears that this will have the same effect with
"[PATCH 08/11] PM / devfreq: Make update_devfreq() public" from Matthias Kaehlcke, doesn't it?
