    usb: host: Add EHCI driver for NVIDIA Tegra SoCs · 79ad3b5a
    Benoit Goby authored
    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).
