Kernel-4.18.0-80.el8_usb-ohci

USB OHCI controllers

Required properties:

  • compatible : “generic-ohci”
  • reg : ohci controller register range (address and length)
  • interrupts : ohci controller interrupt

Optional properties:

  • big-endian-regs : boolean, set this for hcds with big-endian registers
  • big-endian-desc : boolean, set this for hcds with big-endian descriptors
  • big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
  • no-big-frame-no : boolean, set if frame_no lives in bits [15:0] of HCCA
  • remote-wakeup-connected: remote wakeup is wired on the platform
  • num-ports : u32, to override the detected port count
  • clocks : a list of phandle + clock specifier pairs
  • phys : see usb-hcd.txt in the current directory
  • resets : a list of phandle + reset specifier pairs

additionally the properties from usb-hcd.txt (in the current directory) are
supported.

Example:

ohci0: usb@1c14400 {
    compatible = "allwinner,sun4i-a10-ohci", "generic-ohci";
    reg = <0x01c14400 0x100>;
    interrupts = <64>;
    clocks = <&usb_clk 6>, <&ahb_gates 2>;
    phys = <&usbphy 1>;
    phy-names = "usb";
};
