Merge tag 'clk-for-linus-3.12' of git://git.linaro.org/people/mturquette/linux

Pull clock framework changes from Michael Turquette: "The common clk framework changes for 3.12 are dominated by clock driver patches, both new drivers and fixes to existing. A high percentage of these are for Samsung platforms like Exynos. Core framework fixes and some new features like automagical clock re-parenting round out the patches" * tag 'clk-for-linus-3.12' of git://git.linaro.org/people/mturquette/linux: (102 commits) clk: only call get_parent if there is one clk: samsung: exynos5250: Simplify registration of PLL rate tables clk: samsung: exynos4: Register PLL rate tables for Exynos4x12 clk: samsung: exynos4: Register PLL rate tables for Exynos4210 clk: samsung: exynos4: Reorder registration of mout_vpllsrc clk: samsung: pll: Add support for rate configuration of PLL46xx clk: samsung: pll: Use new registration method for PLL46xx clk: samsung: pll: Add support for rate configuration of PLL45xx clk: samsung: pll: Use new registration method for PLL45xx clk: samsung: exynos4: Rename exynos4_plls to exynos4x12_plls clk: samsung: exynos4: Remove checks for DT node clk: samsung: exynos4: Remove unused static clkdev aliases clk: samsung: Modify _get_rate() helper to use __clk_lookup() clk: samsung: exynos4: Use separate aliases for cpufreq related clocks clocksource: samsung_pwm_timer: Get clock from device tree ARM: dts: exynos4: Specify PWM clocks in PWM node pwm: samsung: Update DT bindings documentation to cover clocks clk: Move symbol export to proper location clk: fix new_parent dereference before null check clk: wm831x: Initialise wm831x pointer on init ...
