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 STMicroelectronics clock crossbar (VCC).
+
+The crossbar can take up to 4 input clocks and control up to 16
+output clocks. Not all inputs or outputs have to be in use in a
+particular instantiation. Each output can be individually enabled,
+select any of the input clocks and apply a divide (by 1,2,4 or 8) to
+that selected clock.
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+
+- compatible : shall be:
+ "st,stih416-clkgenc", "st,vcc"
+ "st,stih416-clkgenf", "st,vcc"
+
+- #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 16
+ 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
+ 16 strings are provided then no clocks will be created
+ for the remaining outputs.
+
+Example:
+
+ CLOCKGEN_C_VCC: CLOCKGEN_C_VCC {
+ #clock-cells = <1>;
+ compatible = "st,stih416-clkgenc", "st,clkgen-vcc";
+ reg = <0xfe8308ac 12>;
+
+ clocks = <&CLK_S_VCC_HD>, <&CLOCKGEN_C 1>,
+ <&CLK_S_TMDS_FROMPHY>, <&CLOCKGEN_C 2>;
+
+ clock-output-names =
+ "CLK_S_PIX_HDMI", "CLK_S_PIX_DVO",
+ "CLK_S_OUT_DVO", "CLK_S_PIX_HD",
+ "CLK_S_HDDAC", "CLK_S_DENC",
+ "CLK_S_SDDAC", "CLK_S_PIX_MAIN",
+ "CLK_S_PIX_AUX", "CLK_S_STFE_FRC_0",
+ "CLK_S_REF_MCRU", "CLK_S_SLAVE_MCRU",
+ "CLK_S_TMDS_HDMI", "CLK_S_HDMI_REJECT_PLL",
+ "CLK_S_THSENS";
+ };
