This was fixed at least in 3.13 (perhaps 3.12 too?) by: config ARCH_TEGRA ... select USB_ARCH_HAS_EHCI if USB_SUPPORT select USB_ULPI if USB_PHY select USB_ULPI_VIEWPORT if USB_PHY I think it'd be better to back-port that patch to stable, for consistency. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Yep agreed. Want to cc that patch to linux-stable instead? The v3.13.x -stable builds are breaking here for T114-only Kconfigs... - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The controllers are EHCI compliant.
Selecting CONFIG_USB_EHCI_TEGRA requires CONFIG_USB_ULPI_VIEWPORT. Otherwise the build can break with: drivers/usb/phy/phy-tegra-usb.c: In function 'ulpi_open': drivers/usb/phy/phy-tegra-usb.c:689:31: error: 'ulpi_viewport_access_ops' undeclared (first use in this function) drivers/usb/phy/phy-tegra-usb.c:689:31: note: each undeclared identifier is reported only once for each function it appears in if CONFIG_USB_ULPI_VIEWPORT is not manually selected. Fix by forcing CONFIG_USB_ULPI_VIEWPORT to be selected when CONFIG_USB_EHCI_TEGRA is selected. Then, since CONFIG_USB_ULPI_VIEWPORT requires CONFIG_USB_ULPI to be selected, add that too. N.B.: ULPI is deprecated on this controller for T114, so it might make sense to split the ULPI support code into a separate file, compiled only if a ULPI PHY is selected.
