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

Pull clock controller fixes from Michael Turquette:
 "Two small fixes for the Zynq clock controller introduced in 3.11-rc1
  and another Exynos clock patch which fixes a regression that prevents
  the video pipeline from functioning on that platform"

* tag 'clk-fixes-for-linus' of git://git.linaro.org/people/mturquette/linux:
  clk: exynos4: Add CLK_GET_RATE_NOCACHE flag for the Exynos4x12 ISP clocks
  clk/zynq/clkc: Add CLK_SET_RATE_PARENT flag to ethernet muxes
  clk/zynq/clkc: Add dedicated spinlock for the SWDT
