Merge branch 'v4.3-rc3-clk' of https://github.com/jamesjjliao/linux into clk-next

Pull mediatek clock support and fixes from James Liao:

"This is a collection of new Mediatek clocks support and fixes.
These patches come from Joe and me, including clock support for
subsystems, GPT and some minor fixes."

* 'v4.3-rc3-clk' of https://github.com/jamesjjliao/linux:
  clk: mediatek: Add USB clock support in MT8173 APMIXEDSYS
  clk: mediatek: Add subsystem clocks of MT8173
  dt-bindings: ARM: Mediatek: Document devicetree bindings for clock controllers
  clk: mediatek: Fix rate and dependency of MT8173 clocks
  clk: mediatek: Add fixed clocks support for Mediatek SoC.
  clk: mediatek: Add __initdata and __init for data and functions
  clk: mediatek: Remove unused code from MT8173.
  clk: mediatek: Removed unused dpi_ck clock from MT8173
  clk: mediatek: add 13mhz clock for MT8173

Mediatek imgsys controller
============================
The Mediatek imgsys controller provides various clocks to the system.
Required Properties:
- compatible: Should be:
- "mediatek,mt8173-imgsys", "syscon"
- #clock-cells: Must be 1
The imgsys controller uses the common clk binding from
Documentation/devicetree/bindings/clock/clock-bindings.txt
The available clocks are defined in dt-bindings/clock/mt*-clk.h.
Example:
imgsys: clock-controller@15000000 {
compatible = "mediatek,mt8173-imgsys", "syscon";
reg = <0 0x15000000 0 0x1000>;
#clock-cells = <1>;
};
