  20                         - Offset of the USB Analog configuration
  21                           register (only for xrx200 and xrx200)
  22 - clocks        : References to the (PMU) "phy" clk gate.
  23 - clock-names   : Must be "phy"
  24 - resets        : References to the RCU USB configuration reset bits.

  30 Example for the USB PHYs on an xRX200 SoC:
  31         usb_phy0: usb2-phy@18 {
  32                 compatible = "lantiq,xrx200-usb2-phy";
  33                 reg = <0x18 4>, <0x38 4>;
  34
  35                 clocks = <&pmu PMU_GATE_USB0_PHY>;
  36                 clock-names = "phy";
  37                 resets = <&reset1 4 4>, <&reset0 4 4>;
  38                 reset-names = "phy", "ctrl";
  39                 #phy-cells = <0>;
