Pull clock framework changes from Michael Turquette:
 "The common clk framework changes for 3.12 are dominated by clock
  driver patches, both new drivers and fixes to existing.  A high
  percentage of these are for Samsung platforms like Exynos.  Core
  framework fixes and some new features like automagical clock
  re-parenting round out the patches"
