- phy_type : Should be one of "ulpi" or "utmi".
- 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.
