Actually the functionality added in this series is independent of the DT 
patch. I posted this DT patch here as DONOTMERGE just so that folks can 
know how to test the functionality.

I understand your concern, and if it was the case that these changes 
were dependent on the DT, I would have waited until the DT patch is 
picked up before posting this series here.

Thanks,
Beleswar
