1* Freescale i.MX ci13xxx usb controllers
2
3Required properties:
4- compatible: Should be "fsl,imx27-usb"
5- reg: Should contain registers location and length
6- interrupts: Should contain controller interrupt
7
8Recommended 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
14Optional 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
