Kernel-4.18.0-80.el8_ohci-st

ST USB OHCI controller

Required properties:

• compatible : must be “st,st-ohci-300x”

• reg : physical base addresses of the controller and length of memory mapped

         region
  

• interrupts : one OHCI controller interrupt should be described here

• clocks : phandle list of usb clocks

• clock-names : should be “ic” for interconnect clock and “clk48”
  See: Documentation/devicetree/bindings/clock/clock-bindings.txt

• phys : phandle for the PHY device

• phy-names : should be “usb”

• resets : phandle to the powerdown and reset controller for the USB IP

• reset-names : should be “power” and “softreset”.

  See: Documentation/devicetree/bindings/reset/reset.txt

Example:

ohci0: usb@fe1ffc00 {
    compatible = "st,st-ohci-300x";
    reg = <0xfe1ffc00 0x100>;
    interrupts = <GIC_SPI 149 IRQ_TYPE_NONE>;
    clocks = <&clk_s_a1_ls 0>,
         <&clockgen_b0 0>;
    clock-names = "ic", "clk48";
    phys = <&usb2_phy>;
    phy-names = "usb";

    resets = <&powerdown STIH416_USB0_POWERDOWN>,
         <&softreset STIH416_USB0_SOFTRESET>;
    reset-names = "power", "softreset";
