+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: Regulator that controls vbus power
+
+Example:
+
+reg_usb_ohci: regulator@0 {
+ compatible = "regulator-fixed";
+ gpio = <&gpio 109 0>;
+ over-current-gpios = <&gpio 36 0>;
+ regulator-boot-on;
+ enable-active-high;
+ regulator-name = "usb_ohci_vbus";
+ regulator-min-microvolt = <5000000>;
+ regulator-max-microvolt = <5000000>;
+};
+
+usb_phy: usb-phy {
+ compatible = "ti,da830-usb-phy";
+ #phy-cells = <1>;
+};
+
+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>;
+};
