The Tegra238 XUDC is similar to that found on the Tegra234 device but only support 3 PHYs compared to the 4 PHYs on the Tegra234. The XUDC binding only defines which of the available PHYs is used by the XUDC controller and the Tegra XUSB pad controller binding [0] defines the PHYs that are available.
