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" * tag 'clk-for-linus-20151104' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (143 commits) clk: qcom: msm8960: Fix dsi1/2 halt bits clk: lpc18xx-cgu: fix potential system hang when disabling unused clocks clk: lpc18xx-ccu: fix potential system hang when disabling unused clocks clk: Add clk_hw_is_enabled() for use by clk providers clk: Add stubs for of_clk_*() APIs when CONFIG_OF=n clk: versatile-icst: fix memory leak clk: Remove clk_{register,unregister}_multiplier() clk: iproc: define Broadcom NS2 iProc clock binding clk: iproc: define Broadcom NSP iProc clock binding clk: ns2: add clock support for Broadcom Northstar 2 SoC clk: iproc: Separate status and control variables clk: iproc: Split off dig_filter clk: iproc: Add PLL base write function clk: nsp: add clock support for Broadcom Northstar Plus SoC clk: iproc: Add PWRCTRL support clk: cygnus: Convert all macros to all caps ARM: cygnus: fix link failures when CONFIG_COMMON_CLK_IPROC is disabled clk: imx31: add missing of_node_put clk: imx27: add missing of_node_put clk: si5351: add missing of_node_put ...
