+DA8XX USB OHCI controller
+
+Required properties:
+
+ - compatible: Should be "ti,da830-ohci"
+ - reg: Should contain one register range i.e. start and length
+ - interrupts: Description of the interrupt line
+ - phys: Phandle for the PHY device
+ - phy-names: Should be "usb-phy"
+
+Optional properties:
+ - vbus-supply: phandle of regulator that controls vbus power / over-current
+
+Example:
+
+ohci: usb@0225000 {
+ compatible = "ti,da830-ohci";
+ reg = <0x225000 0x1000>;
+ interrupts = <59>;
+ phys = <&usb_phy 1>;
+ phy-names = "usb-phy";
+ vbus-supply = <&reg_usb_ohci>;
+};
