USB NOP PHY Required properties: - compatible: should be usb-nop-xceiv - #phy-cells: Must be 0 Optional properties: - clocks: phandle to the PHY clock. Use as per Documentation/devicetree /bindings/clock/clock-bindings.txt This property is required if clock-frequency is specified. - clock-names: Should be "main_clk" - clock-frequency: the clock frequency (in Hz) that the PHY clock must be configured to. - vcc-supply: phandle to the regulator that provides power to the PHY. - reset-gpios: Should specify the GPIO for reset. - vbus-detect-gpio: should specify the GPIO detecting a VBus insertion (see Documentation/devicetree/bindings/gpio/gpio.txt) - vbus-regulator : should specifiy the regulator supplying current drawn from the VBus line (see Documentation/devicetree/bindings/regulator/regulator.txt). Example: hsusb1_phy { compatible = "usb-nop-xceiv"; clock-frequency = <19200000>; clocks = <&osc 0>; clock-names = "main_clk"; vcc-supply = <&hsusb1_vcc_regulator>; reset-gpios = <&gpio1 7 GPIO_ACTIVE_LOW>; vbus-detect-gpio = <&gpio2 13 GPIO_ACTIVE_HIGH>; vbus-regulator = <&vbus_regulator>; #phy-cells = <0>; }; hsusb1_phy is a NOP USB PHY device that gets its clock from an oscillator and expects that clock to be configured to 19.2MHz by the NOP PHY driver. hsusb1_vcc_regulator provides power to the PHY and GPIO 7 controls RESET. GPIO 13 detects VBus insertion, and accordingly notifies the vbus-regulator.
