- nvidia,vbus-gpio : If present, specifies a gpio that needs to be
activated for the bus to be powered.
Required properties for phy_type == ulpi:
- nvidia,phy-reset-gpio : The GPIO used to reset the PHY.
Optional properties:
- dr_mode : dual role mode. Indicates the working mode for
nvidia,tegra20-ehci compatible controllers. Can be "host", "peripheral",
