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>;
};
