Merge tag 'clk-for-linus-3.19' of git://git.linaro.org/people/mike.turquette/linux

Pull clk framework updates from Mike Turquette:
 "This is much later than usual due to several last minute bugs that had
  to be addressed.  As usual the majority of changes are new drivers and
  modifications to existing drivers.  The core recieved many fixes along
  with the groundwork for several large changes coming in the future
  which will better parition clock providers from clock consumers"
