14 The Tegra XUSB pad controller manages a set of I/O lanes (with differential
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
33 PHY bindings, as described by the phy-bindings.txt file in this directory.
36 pad controller and the XUSB controller as "ports". This is confusing since
37 "port" is typically used to denote the physical USB receptacle. The device
39 abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
40 for the USB signal, the VBUS power supply, the USB 2.0 companion port for
41 USB 3.0 receptacles, ...).
