     BROADCOM NORTHSTAR2 USB2 (DUAL ROLE DEVICE) PHY
     
     Required properties:
      - compatible: brcm,ns2-drd-phy
      - reg: offset and length of the NS2 PHY related registers.
      - reg-names
        The below registers must be provided.
        icfg - for DRD ICFG configurations
        rst-ctrl - for DRD IDM reset
       crmu-ctrl - for CRMU core vdd, PHY and PHY PLL reset
       usb2-strap - for port over current polarity reversal
     - #phy-cells: Must be 0. No args required.
     - vbus-gpios: vbus gpio binding
     - id-gpios: id gpio binding
    
    Refer to phy/phy-bindings.txt for the generic PHY binding properties
    
    Example:
            usbdrd_phy: phy@66000960 {
                            #phy-cells = <0>;
                            compatible = "brcm,ns2-drd-phy";
                            reg = <0x66000960 0x24>,
                                  <0x67012800 0x4>,
                                  <0x6501d148 0x4>,
                                  <0x664d0700 0x4>;
                            reg-names = "icfg", "rst-ctrl",
                                        "crmu-ctrl", "usb2-strap";
                            id-gpios = <&gpio_g 30 0>;
                            vbus-gpios = <&gpio_g 31 0>;
            };
