+
+Required properties:
+- compatible: Should be "fsl,imx27-usb"
+- reg: Should contain registers location and length
+- interrupts: Should contain controller interrupt
+
+Recommended properies:
+- phy_type: the type of the phy connected to the core. Should be one
+  of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
+  property the PORTSC register won't be touched
+- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"

+- 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;
+};
