+* Freescale i.MX ci13xxx usb controllers
+
+Required properties:
+- compatible: Should be "fsl,imx27-usb"
+- reg: Should contain registers location and length
+- interrupts: Should contain controller interrupt
+
+Optional properties:
+- fsl,usbphy: phandler of usb phy that connects to the only one port
+- fsl,usbmisc: phandler of non-core register device, with one argument
+ that indicate usb controller index
+- vbus-supply: regulator for vbus
+- disable-over-current: disable over current detect
+- external-vbus-divider: enables off-chip resistor divider for Vbus
+
+Examples:
+usb@02184000 { /* USB OTG */
+ compatible = "fsl,imx6q-usb", "fsl,imx27-usb";
+ reg = <0x02184000 0x200>;
+ interrupts = <0 43 0x04>;
+ fsl,usbphy = <&usbphy1>;
+ fsl,usbmisc = <&usbmisc 0>;
+ disable-over-current;
+ external-vbus-divider;
+};
