Merge tag 'for_3.17/samsung-clk' of git://git.kernel.org/pub/scm/linux/kernel/git/tfiga/samsung-clk into clk-next-samsung
Samsung clock patches for 3.17 1) non-critical fixes (without need to push to stable): d5e136a clk: samsung: Register clk provider only after registering its all clocks 305cfab clk: samsung: Make of_device_id array const e9d5295 clk: samsung: exynos5420: Setup clocks before system suspend f65d518 clk: samsung: trivial: Correct typo in author's name 2) Exynos CLKOUT driver: 800c979 clk: samsung: exynos4: Add missing CPU/DMC clock hierarchy 01f7ec2 clk: samsung: exynos4: Add CLKOUT clock hierarchy 1e832e5 clk: samsung: Add driver to control CLKOUT line on Exynos SoCs d19bb39 ARM: dts: exynos: Update PMU node with CLKOUT related data 3) Clock hierarchy extensions: 17d3f1d clk: exynos4: Add PPMU IP block source clocks. ca5b402 clk: samsung: register exynos5420 apll/kpll configuration data 4) ARM CLKDOWN functionality enablement for Exynos4 and 3250: 42773b2 clk: samsung: exynos4: Enable ARMCLK down feature 45c5b0a clk: samsung: exynos3250: Enable ARMCLK down feature
