14 The Tegra XUSB pad controller manages a set of I/O lanes (with differential
16 is controlled by a HW block referred to as a "pad" in the Tegra hardware
17 documentation. Each such "pad" may control either one or multiple lanes,
21 Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
22 super-speed USB. Other lanes are for various types of low-speed, full-speed
23 or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
24 contains a software-configurable mux that sits between the I/O controller
27 In addition to per-lane configuration, USB 3.0 ports may require additional
28 settings on a per-board basis.
30 Pads will be represented as children of the top-level XUSB pad controller
31 device tree node. Each lane exposed by the pad will be represented by its
33 PHY bindings, as described by the phy-bindings.txt file in this directory.
