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 ...

+Binding for a type of quad channel digital frequency synthesizer found on
+certain STMicroelectronics consumer electronics SoC devices.
+
+This version contains a programmable PLL which can generate up to 216, 432
+or 660MHz (from a 30MHz oscillator input) as the input to the digital
+synthesizers.
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be:
+ "st,stih416-quadfs216", "st,quadfs"
+ "st,stih416-quadfs432", "st,quadfs"
+ "st,stih416-quadfs660-E", "st,quadfs"
+ "st,stih416-quadfs660-F", "st,quadfs"
+
+- #clock-cells : from common clock binding; shall be set to 1.
+
+- reg : A Base address and length of the register set.
+
+- clocks : from common clock binding
+
+- clock-output-names : From common clock binding. The block has 4
+ clock outputs but not all of them in a specific instance
+ have to be used in the SoC. If a clock name is left as
+ an empty string then no clock will be created for the
+ output associated with that string index. If fewer than
+ 4 strings are provided then no clocks will be created
+ for the remaining outputs.
+
+Example:
+
+ CLOCKGEN_E: CLOCKGEN_E {
+ #clock-cells = <1>;
+ compatible = "st,stih416-quadfs660-E", "st,quadfs";
+ reg = <0xfd3208bc 0xB0>;
+
+ clocks = <&CLK_SYSIN>;
+ clock-output-names = "CLK_M_PIX_MDTP_0",
+ "CLK_M_PIX_MDTP_1",
+ "CLK_M_PIX_MDTP_2",
+ "CLK_M_MPELPC";
+ };
