Required properties:
- compatible: should be usb-nop-xceiv
Optional properties:
- clocks: phandle to the PHY clock. Use as per Documentation/devicetree
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).

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.
