IMG Pistachio USB PHY
|
|
=====================
|
|
|
|
Required properties:
|
|
--------------------
|
|
- compatible: Must be "img,pistachio-usb-phy".
|
|
- #phy-cells: Must be 0. See ./phy-bindings.txt for details.
|
|
- clocks: Must contain an entry for each entry in clock-names.
|
|
See ../clock/clock-bindings.txt for details.
|
|
- clock-names: Must include "usb_phy".
|
|
- img,cr-top: Must constain a phandle to the CR_TOP syscon node.
|
|
- img,refclk: Indicates the reference clock source for the USB PHY.
|
|
See <dt-bindings/phy/phy-pistachio-usb.h> for a list of valid values.
|
|
|
|
Optional properties:
|
|
--------------------
|
|
- phy-supply: USB VBUS supply. Must supply 5.0V.
|
|
|
|
Example:
|
|
--------
|
|
usb_phy: usb-phy {
|
|
compatible = "img,pistachio-usb-phy";
|
|
clocks = <&clk_core CLK_USB_PHY>;
|
|
clock-names = "usb_phy";
|
|
phy-supply = <&usb_vbus>;
|
|
img,refclk = <REFCLK_CLK_CORE>;
|
|
img,cr-top = <&cr_top>;
|
|
#phy-cells = <0>;
|
|
};
