Merge tag 'clk-for-linus-3.14-part2' of git://git.linaro.org/people/mike.turquette/linux
Pull more clock framework changes from Mike Turquette: "The second half of the clock framework pull requeust for 3.14 is dominated by platform support for Qualcomm's MSM SoCs, DT binding updates for TI's OMAP-ish processors and additional support for Samsung chips. Additionally there are other smaller clock driver changes and several last minute fixes. This pull request also includes the HiSilicon support that depends on the already-merged arm-soc pull request" [ Fix up stupid compile error in the source tree with evil merge - Grumpy Linus ] * tag 'clk-for-linus-3.14-part2' of git://git.linaro.org/people/mike.turquette/linux: (49 commits) clk: sort Makefile clk: sunxi: fix overflow when setting up divided factors clk: Export more clk-provider functions dt-bindings: qcom: Fix warning with duplicate dt define clk: si5351: remove variant from platform_data clk: samsung: Remove unneeded semicolon clk: qcom: Fix modular build ARM: OMAP3: use DT clock init if DT data is available ARM: AM33xx: remove old clock data and link in new clock init code ARM: AM43xx: Enable clock init ARM: OMAP: DRA7: Enable clock init ARM: OMAP4: remove old clock data and link in new clock init code ARM: OMAP2+: io: use new clock init API ARM: OMAP2+: PRM: add support for initializing PRCM clock modules from DT ARM: OMAP3: hwmod: initialize clkdm from clkdm_name ARM: OMAP: hwmod: fix an incorrect clk type cast with _get_clkdm ARM: OMAP2+: clock: use driver API instead of direct memory read/write ARM: OMAP2+: clock: add support for indexed memmaps ARM: dts: am43xx clock data ARM: dts: AM35xx: use DT clock data ...

+Binding for Texas Instruments APLL clock.
+
+Binding status: Unstable - ABI compatibility may be broken in the future
+
+This binding uses the common clock binding[1]. It assumes a
+register-mapped APLL with usually two selectable input clocks
+(reference clock and bypass clock), with analog phase locked
+loop logic for multiplying the input clock to a desired output
+clock. This clock also typically supports different operation
+modes (locked, low power stop etc.) APLL mostly behaves like
+a subtype of a DPLL [2], although a simplified one at that.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] Documentation/devicetree/bindings/clock/ti/dpll.txt
+
+Required properties:
+- compatible : shall be "ti,dra7-apll-clock"
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
+- reg : address and length of the register set for controlling the APLL.
+ It contains the information of registers in the following order:
+ "control" - contains the control register base address
+ "idlest" - contains the idlest register base address
+
+Examples:
+ apll_pcie_ck: apll_pcie_ck@4a008200 {
+ #clock-cells = <0>;
+ clocks = <&apll_pcie_in_clk_mux>, <&dpll_pcie_ref_ck>;
+ reg = <0x4a00821c 0x4>, <0x4a008220 0x4>;
+ compatible = "ti,dra7-apll-clock";
+ };
