-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.
