Merge tag 'clk-for-linus-3.15' of git://git.linaro.org/people/mike.turquette/linux

Pull clock framework changes from Mike Turquette:
 "The clock framework changes for 3.15 look similar to past pull
  requests.  Mostly clock driver updates, more Device Tree support in
  the form of common functions useful across platforms and a handful of
  features and fixes to the framework core"
