NVIDIA Tegra device tree bindings
-------------------------------------------
Boards with the tegra20 SoC shall have the following properties:
Required root node property:
compatible = "nvidia,tegra20";
Boards with the tegra30 SoC shall have the following properties:
Required root node property:
compatible = "nvidia,tegra30";

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.
