Merge tag 'clk-for-linus-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clock framework updates from Michael Turquette: "The changes to the common clock framework for 4.2 are dominated by new drivers and updates to existing ones, as usual. There are some fixes to the framework itself and several cleanups for sparse warnings, etc" * tag 'clk-for-linus-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (135 commits) clk: stm32: Add clock driver for STM32F4[23]xxx devices dt-bindings: Document the STM32F4 clock bindings cpufreq: exynos: remove Exynos4210 specific cpufreq driver support ARM: Exynos: switch to using generic cpufreq driver for Exynos4210 clk: samsung: exynos4: add cpu clock configuration data and instantiate cpu clock clk: samsung: add infrastructure to register cpu clocks clk: add CLK_RECALC_NEW_RATES clock flag for Exynos cpu clock support doc: dt: add documentation for lpc1850-ccu clk driver clk: add lpc18xx ccu clk driver doc: dt: add documentation for lpc1850-cgu clk driver clk: add lpc18xx cgu clk driver clk: keystone: add support for post divider register for main pll clk: mvebu: flag the crypto clk as CLK_IGNORE_UNUSED clk: cygnus: remove Cygnus dummy clock binding clk: cygnus: add clock support for Broadcom Cygnus clk: Change bcm clocks build dependency clk: iproc: add initial common clock support clk: iproc: define Broadcom iProc clock binding MAINTAINERS: update email for Michael Turquette clk: meson: add some error handling in meson_clk_register_cpu() ...
