Merge tag 'clk-for-linus-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clock framework updates from Michael Turquette:
 "The changes to the common clock framework for 4.2 are dominated by new
  drivers and updates to existing ones, as usual.

  There are some fixes to the framework itself and several cleanups for
  sparse warnings, etc"
