Merge tag 'clk-for-linus-3.13' of git://git.linaro.org/people/mturquette/linux

Pull clock framework changes from Mike Turquette:
 "The clock changes for 3.13 are an even mix of framework improvements &
  bug fixes along with updates to existing clock drivers and the
  additional of new clock drivers"
