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

Pull more clk updates from Stephen Boyd:
 "Here's some more updates that missed the last pull request because I
  happened to tag the tree at an earlier point in the history of
  clk-next. I must have fat fingered it and checked out an older version
  of clk-next on this second computer I'm using.

  This time it actually includes more code for Qualcomm SoCs, the AT91
  major updates, and some Rockchip SoC clk driver updates as well. I've
  corrected this flow so this shouldn't happen again"
