Merge tag 'clk-for-linus-3.19' of git://git.linaro.org/people/mike.turquette/linux
Pull clk framework updates from Mike Turquette: "This is much later than usual due to several last minute bugs that had to be addressed. As usual the majority of changes are new drivers and modifications to existing drivers. The core recieved many fixes along with the groundwork for several large changes coming in the future which will better parition clock providers from clock consumers" * tag 'clk-for-linus-3.19' of git://git.linaro.org/people/mike.turquette/linux: (86 commits) clk: samsung: Fix Exynos 5420 pinctrl setup and clock disable failure due to domain being gated ARM: OMAP3: clock: fix boot breakage in legacy mode ARM: OMAP2+: clock: fix DPLL code to use new determine rate APIs clk: Really fix deadlock with mmap_sem clk: mmp: fix sparse non static symbol warning clk: Change clk_ops->determine_rate to return a clk_hw as the best parent clk: change clk_debugfs_add_file to take a struct clk_hw clk: Don't expose __clk_get_accuracy clk: Don't try to use a struct clk* after it could have been freed clk: Remove unused function __clk_get_prepare_count clk: samsung: Fix double add of syscore ops after driver rebind clk: samsung: exynos4: set parent of sclk_hdmiphy to hdmi clk: samsung: exynos4415: Fix build with PM_SLEEP disabled clk: samsung: remove unnecessary inclusion of header files from clk.h clk: samsung: remove unnecessary CONFIG_OF from clk.c clk: samsung: Spelling s/bwtween/between/ clk: rockchip: Add support for the mmc clock phases using the framework clk: rockchip: add bindings for the mmc clocks clk: rockchip: rk3288 export i2s0_clkout for use in DT clk: rockchip: use clock ID for DMC (memory controller) on rk3288 ...
