Merge tag 'clk-for-linus-20151104' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "The majority of the changes are driver updates and new device support.
  The core framework is mostly unchanged this time around, with only a
  couple patches to expose a clk provider API and make getting clk
  parent names from DT more robust.

  Driver updates:

   - Support for clock controllers found on Broadcom Northstar SoCs and
     bcm2835 SoC

   - Support for Allwinner audio clocks

   - A few cleanup patches for Tegra drivers and support for the highest
     DFLL frequencies on Tegra124

   - Samsung exynos7 fixes and improvements

   - i.Mx SoC updates to add a few missing clocks and keep debug uart
     clocks on during kernel intialization

   - Some mediatek cleanups and support for more subsystem clocks

   - Support for msm8916 gpu/audio clocks and qcom's GDSC power domain
     controllers

   - A new driver for the Silabs si514 clock chip"
