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

Pull clock driver fixes from Mike Turquette:
 "This batch of fixes is for a handful of clock drivers from Allwinner,
  Samsung, ST & TI.  Most of them are of the "this hardware won't work
  without this fix" variety, including patches that fix platforms that
  did not boot under certain configurations.  Other fixes are the result
  of changes to the clock core introduced in 3.15 that had subtle
  impacts on the clock drivers.

  There are no fixes to the clock framework core in this pull request"
