description: |
|
||
|
|
The Tegra XUSB pad controller manages a set of I/O lanes (with differential
|
||
|
|
signals) which connect directly to pins/pads on the SoC package. Each lane
|
||
|
|
is controlled by a HW block referred to as a "pad" in the Tegra hardware
|
||
|
|
documentation. Each such "pad" may control either one or multiple lanes,
|
||
|
|
and thus contains any logic common to all its lanes. Each lane can be
|
||
|
|
separately configured and powered up.
|
||
|
|
|
||
|
|
Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
|
||
|
|
super-speed USB. Other lanes are for various types of low-speed, full-speed
|
||
|
|
or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
|
||
|
|
contains a software-configurable mux that sits between the I/O controller
|
||
|
|
ports (e.g. PCIe) and the lanes.
|
||
|
|
|
||
|
|
In addition to per-lane configuration, USB 3.0 ports may require additional
|
||
|
|
settings on a per-board basis.
|
||
|
|
|
||
|
|
Pads will be represented as children of the top-level XUSB pad controller
|
||
|
|
device tree node. Each lane exposed by the pad will be represented by its
|
||
|
|
own subnode and can be referenced by users of the lane using the standard
|
||
|
|
PHY bindings, as described by the phy-bindings.txt file in this directory.
|
||
|
|
|
||
|
|
The Tegra hardware documentation refers to the connection between the XUSB
|
||
|
|
pad controller and the XUSB controller as "ports". This is confusing since
|
||
|
|
"port" is typically used to denote the physical USB receptacle. The device
|
||
|
|
tree binding in this document uses the term "port" to refer to the logical
|
||
|
|
abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
|
||
|
|
for the USB signal, the VBUS power supply, the USB 2.0 companion port for
|
||
|
|
USB 3.0 receptacles, ...).
