The Tegra 2 SoC has 3 EHCI compatible USB controllers. This patch adds the necessary glue to allow the ehci-hcd driver to work on Tegra 2 SoCs. The platform data is used to configure board-specific phy settings and to configure the operating mode, as one of the ports may be used as a otg port. For additional power saving, the driver supports powering down the phy on bus suspend when it is used, for example, to connect an internal device that use an out-of-band remote wakeup mechanism (e.g. a gpio).
