Hi Mr. Kim,

It's maybe missing for v3.3 merge at samsung soc.
Please give your opinion, how to handle it?

Looks ok to me at the moment, and as a note, I'm sorting it out now.


If you don't mind it, it can merge it by devfreq.

Hmm, I think, it should be handled in samsung tree to avoid useless conflicts with others. And if you need this in the devfreq tree now, please let me know so that I can create topic branch for it.

Thanks.

Best regards,
Kgene.
