1	* Freescale i.MX ci13xxx usb controllers
2	
3	Required properties:
4	- compatible: Should be "fsl,imx27-usb"
5	- reg: Should contain registers location and length
6	- interrupts: Should contain controller interrupt
7	
8	Recommended properies:
9	- phy_type: the type of the phy connected to the core. Should be one
10	  of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
11	  property the PORTSC register won't be touched
12	- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
13	
14	Optional properties:
15	- fsl,usbphy: phandler of usb phy that connects to the only one port
16	- fsl,usbmisc: phandler of non-core register device, with one argument
17	  that indicate usb controller index
18	- vbus-supply: regulator for vbus
19	- disable-over-current: disable over current detect
20	- external-vbus-divider: enables off-chip resistor divider for Vbus
21	- maximum-speed: limit the maximum connection speed to "full-speed".
22	
23	Examples:
24	usb@02184000 { /* USB OTG */
25		compatible = "fsl,imx6q-usb", "fsl,imx27-usb";
26		reg = <0x02184000 0x200>;
27		interrupts = <0 43 0x04>;
28		fsl,usbphy = <&usbphy1>;
29		fsl,usbmisc = <&usbmisc 0>;
30		disable-over-current;
31		external-vbus-divider;
32		maximum-speed = "full-speed";
33	};
