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.
