1 Device tree binding for NVIDIA Tegra XUSB pad controller
4 The Tegra XUSB pad controller manages a set of I/O lanes (with differential
13 or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
20 Pads will be represented as children of the top-level XUSB pad controller
25 The Tegra hardware documentation refers to the connection between the XUSB
26 pad controller and the XUSB controller as "ports". This is confusing since
