Applied patches [1-9/14] to cpufreq and OPP trees and done some reordering as well to keep all binding patches together. Rob's Ack is missing on two of the binding patches and I will add them later once he provides it. Everything should be available here for you to base rest of the stuff. git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/arm/linux-next -- viresh
