From: Thierry Reding <treding@xxxxxxxxxx> [ Upstream commit 0d5c9bc7c68009af04bbadf22306467674c6fb90 ] The usb_get_maximum_speed() function is part of the usb-common module, so enable it by selecting the corresponding Kconfig symbol. While at it, also make sure to depend on USB_SUPPORT because USB_PHY requires that. This can lead to Kconfig conflicts if USB_SUPPORT is not enabled while attempting to enable PHY_TEGRA_XUSB.
