+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>;
+};
