    I don't believe the Tegra USB driver supports gadget mode at present.
    Would the above be better written as:

    select USB if USB_SUPPORT

    And I wonder if the Tegra EHCI driver shouldn't be doing some of these
    selects, not the ARCH_TEGRA_* option.

    And this is probably required for Tegra30 too not just Tegra20.
