Qualcomm’s APQ8016/MSM8916 USB transceiver controller

  • compatible:
    Usage: required
    Value type:
    Definition: Should contain “qcom,usb-8x16-phy”.

  • reg:
    Usage: required
    Value type:
    Definition: USB PHY base address and length of the register map

  • clocks:
    Usage: required
    Value type:
    Definition: See clock-bindings.txt section “consumers”. List of

              two clock specifiers for interface and core controller
              clocks.
    
  • clock-names:
    Usage: required
    Value type:
    Definition: Must contain “iface” and “core” strings.

  • vddcx-supply:
    Usage: required
    Value type:
    Definition: phandle to the regulator VDCCX supply node.

  • v1p8-supply:
    Usage: required
    Value type:
    Definition: phandle to the regulator 1.8V supply node.

    Definition: phandle to the regulator 3.3V supply node.

  • resets:
    Usage: required
    Value type:
    Definition: See reset.txt section “consumers”. PHY reset specifier.

  • reset-names:
    Usage: required
    Value type:
    Definition: Must contain “phy” string.

  • switch-gpio:
    Usage: optional
    Value type:
    Definition: Some boards are using Dual SPDT USB Switch, witch is

              controlled by GPIO to de/multiplex D+/D- USB lines
              between connectors.
    

Example:
usb_phy: phy@78d9000 {
compatible = “qcom,usb-8x16-phy”;
reg = <0x78d9000 0x400>;

    vddcx-supply = <&pm8916_s1_corner>;
    v1p8-supply = <&pm8916_l7>;
    v3p3-supply = <&pm8916_l13>;

    clocks = <&gcc GCC_USB_HS_AHB_CLK>,
             <&gcc GCC_USB_HS_SYSTEM_CLK>;
    clock-names = "iface", "core";

    resets = <&gcc GCC_USB2A_PHY_BCR>;
    reset-names = "phy";

    // D+/D- lines: 1 - Routed to HUB, 0 - Device connector
    switch-gpio = <&pm8916_gpios 4 GPIO_ACTIVE_HIGH>;
