  - nvidia,vbus-gpio : If present, specifies a gpio that needs to be
    activated for the bus to be powered.

+Optional properties:
+  - dr_mode : dual role mode. Indicates the working mode for
+   nvidia,tegra20-ehci compatible controllers.  Can be "host", "peripheral",
+   or "otg".  Default to "host" if not defined for backward compatibility.
+      host means this is a host controller
+      peripheral means it is device controller
+      otg means it can operate as either ("on the go")
+  - nvidia,has-legacy-mode : boolean indicates whether this controller can
+    operate in legacy mode (as APX 2500 / 2600). In legacy mode some
+    registers are accessed through the APB_MISC base address instead of
+    the USB controller. Since this is a legacy issue it probably does not
+    warrant a compatible string of its own.
