Merge tag 'clk-for-linus-3.15' of git://git.linaro.org/people/mike.turquette/linux
Pull clock framework changes from Mike Turquette: "The clock framework changes for 3.15 look similar to past pull requests. Mostly clock driver updates, more Device Tree support in the form of common functions useful across platforms and a handful of features and fixes to the framework core" * tag 'clk-for-linus-3.15' of git://git.linaro.org/people/mike.turquette/linux: (86 commits) clk: shmobile: fix setting paretn clock rate clk: shmobile: rcar-gen2: fix lb/sd0/sd1/sdh clock parent to pll1 clk: Fix minor errors in of_clk_init() function comments clk: reverse default clk provider initialization order in of_clk_init() clk: sirf: update copyright years to 2014 clk: mmp: try to use closer one when do round rate clk: mmp: fix the wrong calculation formula clk: mmp: fix wrong mask when calculate denominator clk: st: Adds quadfs clock binding clk: st: Adds clockgen-vcc and clockgen-mux clock binding clk: st: Adds clockgen clock binding clk: st: Adds divmux and prediv clock binding clk: st: Support for A9 MUX clocks clk: st: Support for ClockGenA9/DDR/GPU clk: st: Support for QUADFS inside ClockGenB/C/D/E/F clk: st: Support for VCC-mux and MUX clocks clk: st: Support for PLLs inside ClockGenA(s) clk: st: Support for DIVMUX and PreDiv Clocks clk: support hardware-specific debugfs entries clk: s2mps11: Use of_get_child_by_name ...
