Merge tag 'clk-for-linus-4.1' 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 4.0 are mostly new clock drivers and updates to existing ones for feature enhancements and bug fixes. There is more churn than usual in the framework core due to the change to introduce per-user unique struct clk pointers in 4.0. This caused several regressions to surface, some of which were sent as fixes to 4.0. New generic clock drivers were added for GPIO- and PWM-based clock controllers. Additionally the common clk-divider code recieved several fixes to the way it rounds rates" * tag 'clk-for-linus-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (91 commits) clk: check ->determine/round_rate() return value in clk_calc_new_rates clk: at91: usb: propagate rate modification to the parent clk clk: samsung: exynos4: Disable ARMCLK down feature on Exynos4210 SoC clk: don't use __initconst for non-const arrays clk: at91: change to using endian agnositc IO clk: clk-gpio-gate: Fix active low clk: Add PWM clock driver clk: Add clock driver for mb86s7x clk: pxa: pxa3xx: add missing os timer clock clk: tegra: Use the proper parent for plld_dsi clk: tegra: Use generic tegra_osc_clk_init() on Tegra114 clk: tegra: Model oscillator as clock clk: tegra: Add peripheral registers for bank Y clk: tegra: Register the proper number of resets clk: tegra: Remove needless initializations clk: tegra: Use consistent indentation clk: tegra: Various whitespace cleanups clk: tegra: Enable HDA to HDMI clocks on Tegra124 clk: tegra: Fix a bunch of sparse warnings clk: tegra: Fix typo tabel -> table ...
