1USB NOP PHY 2 3Required properties: 4- compatible: should be usb-nop-xceiv 5 6Optional 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-supply: phandle to the regulator that provides power to the PHY. 19 20Example: 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-supply = <&hsusb1_reset_regulator>; 29 }; 30 31hsusb1_phy is a NOP USB PHY device that gets its clock from an oscillator 32and expects that clock to be configured to 19.2MHz by the NOP PHY driver. 33hsusb1_vcc_regulator provides power to the PHY and hsusb1_reset_regulator 34controls RESET. 35
