Merge tag 'clk-for-linus-3.11' of git://git.linaro.org/people/mturquette/linux

Pull clock framework updates from Mike Turquette:
 "The common clock framework changes for 3.11 include new clock drivers
  across several different platforms and architectures, fixes to
  existing drivers, a MAINTAINERS file fix and improvements to the basic
  clock types that allow them to be of use to more platforms than before.

  Only a few fixes to the core framework are included with most all of
  the changes landing in the various clock drivers themselves."
