| Required properties: |
| - compatible: Should be "fsl,imx27-usb" |
| - reg: Should contain registers location and length |
| - interrupts: Should contain controller interrupt |
| - fsl,usbphy: phandle of usb phy that connects to the port |
| |
| 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 |
