| * 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 |
| |
| 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 |

| - dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg" |
| |
| 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 |
| - maximum-speed: limit the maximum connection speed to "full-speed". |

| 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; |
| maximum-speed = "full-speed"; |
| }; |
