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

Pull clock framework update from Michael Turquette:
 "The common clock framework changes for 3.9 are almost entirely fixes.

  None are dire enough to be Cc'd to stable which may be interpreted to
  mean that users of the framework are reaching stability.  Lots of new
  adoption of this framework is via DeviceTree data and that comes
  through the respective architecture and platform trees instead of
  through the clk framework tree.

  Two new features are improved debugfs output and an improvement to how
  DT clocks are initialized by reusing a common method."
