+
+ - reg: Offset and length of the USB controller register set.
+
+ - interrupts: The USB interrupt number.
+
+ - interrupt-names: Should be set to "mc".
+
+ - dr_mode: The USB operation mode. Should be one of "host", "peripheral" or "otg".

+ - vbus-supply: Phandle to a regulator providing the USB bus power.
+
+Example:
+       usb_phy: usb-phy {
+               compatible = "ti,da830-usb-phy";
+               #phy-cells = <0>;
+               status = "okay";
+       };
+       usb0: usb@200000 {
+               compatible = "ti,da830-musb";
+               reg =   <0x00200000 0x10000>;
+               interrupts = <58>;
+               interrupt-names = "mc";
+
+               dr_mode = "host";
+               vbus-supply = <&usb_vbus>;
+               phys = <&usb_phy 0>;
+               phy-names = "usb-phy";
