| USB NOP PHY |
| |
| Required properties: |
| - compatible: should be usb-nop-xceiv |
| |
| 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 RESET to the PHY. |
| |
| - reset-supply: phandle to the regulator that provides power to the PHY. |
| |
| Example: |
| |
| hsusb1_phy { |
| compatible = "usb-nop-xceiv"; |
| clock-frequency = <19200000>; |
| clocks = <&osc 0>; |
| clock-names = "main_clk"; |
| vcc-supply = <&hsusb1_vcc_regulator>; |
| reset-supply = <&hsusb1_reset_regulator>; |
| }; |
| |
| 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 hsusb1_reset_regulator |
| controls RESET. |
