-Tegra SOC USB controllers
-
-The device node for a USB controller that is part of a Tegra
-SOC is as described in the document "Open Firmware Recommended
-Practice : Universal Serial Bus" with the following modifications
-and additions :
-
-Required properties :
- - compatible : Should be "nvidia,tegra20-ehci" for USB controllers
-   used in host mode.
- - 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.
