+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"
+
If these are required, shouldn't they say "Must" instead of "Should"?
+Optional properties:
+ - vbus-gpio: If present, specifies a gpio that needs to be
+ activated for the bus to be powered.
+ - oci-gpio: If present, specifies a gpio that needs to be
+ activated for the overcurrent detection.
+ - power_on_delay: Power On to Power Good time - in ms.
+
+Example for omap138-lck:
+
+usb_phy: usb-phy {
+ compatible = "ti,da830-usb-phy";
+ #phy-cells = <1>;
+ status = "disabled";
+};
+usb11: usb11@0225000 {
+ compatible = "ti,da830-ohci";
+ reg = <0x225000 0x1000>;
+ interrupts = <59>;
+ phys = <&usb_phy 1>;
+ phy-names = "usb-phy";
+ status = "disabled";
+};
