   1 USB NOP PHY
   2
   3 Required properties:
   4 - compatible: should be usb-nop-xceiv
   5
   6 Optional properties:
   7 - clocks: phandle to the PHY clock. Use as per Documentation/devicetree
   8   /bindings/clock/clock-bindings.txt
   9   This property is required if clock-frequency is specified.
  10
  11 - clock-names: Should be "main_clk"
  12
  13 - clock-frequency: the clock frequency (in Hz) that the PHY clock must
  14   be configured to.
  15
  16 - vcc-supply: phandle to the regulator that provides RESET to the PHY.
  17
  18 - reset-gpios: Should specify the GPIO for reset.

  20 Example:
  21
  22         hsusb1_phy {
  23                 compatible = "usb-nop-xceiv";
  24                 clock-frequency = <19200000>;
  25                 clocks = <&osc 0>;
  26                 clock-names = "main_clk";
  27                 vcc-supply = <&hsusb1_vcc_regulator>;
  28                 reset-gpios = <&gpio1 7 GPIO_ACTIVE_LOW>;
  29         };
  30
  31 hsusb1_phy is a NOP USB PHY device that gets its clock from an oscillator
  32 and expects that clock to be configured to 19.2MHz by the NOP PHY driver.
  33 hsusb1_vcc_regulator provides power to the PHY and GPIO 7 controls RESET.
