Merge tag 'clk-for-linus-3.17' of git://git.linaro.org/people/mike.turquette/linux
Pull clock framework updates from Mike Turquette:
 "The clock framework changes for 3.17 are mostly additions of new clock
  drivers and fixes/enhancements to existing clock drivers.  There are
  also some non-critical fixes and improvements to the framework core.

  Changes to the clock framework core include:
   - improvements to printks on errors
   - flattening the previously hierarchal structure of per-clock entries
     in debugfs
   - allow per-clock debugfs entries that are specific to a particular
     clock driver
   - configure initial clock parent and/or initial clock rate from
     Device Tree
   - several feature enhancements to the composite clock type
   - misc fixes

  New clock drivers added include:
   - TI Palmas PMIC
   - Allwinner A23 SoC
   - Qualcomm APQ8084 and IPQ8064 SoCs
   - Rockchip rk3188, rk3066 and rk3288 SoCs
   - STMicroelectronics STiH407 SoC
   - Cirrus Logic CLPS711X SoC

  Many fixes, feature enhancements and further clock tree support for
  existing clock drivers also were merged, such as Samsung's "ARMCLK
  down" power saving feature for their Exynos4 & Exynos5 SoCs"
