-Device tree binding for NVIDIA Tegra XUSB pad controller
-========================================================
-
-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, ...).
-
-Required properties:
---------------------
-- compatible: Must be:

-
-Pad nodes:
-==========
-
-A required child node named "pads" contains a list of subnodes, one for each
-of the pads exposed by the XUSB pad controller. Each pad may need additional
-resources that can be referenced in its pad node.
-
-The "status" property is used to enable or disable the use of a pad. If set
-to "disabled", the pad will not be used on the given board. In order to use
-the pad and any of its lanes, this property must be set to "okay".
-
-For Tegra124 and Tegra132, the following pads exist: usb2, ulpi, hsic, pcie
-and sata. No extra resources are required for operation of these pads.
-
-For Tegra210, the following pads exist: usb2, hsic, pcie and sata. Below is
-a description of the properties of each pad.
-
-UTMI pad:
----------
-
-Required properties:
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Must contain the following entries:
- - "trk": phandle and specifier referring to the USB2 tracking clock
-
-HSIC pad:
----------
-
-Required properties:
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Must contain the following entries:
- - "trk": phandle and specifier referring to the HSIC tracking clock
-

- - "phy": reset for the SATA UPHY block
-
-
-PHY nodes:
-==========

-Each pad node has a child named "lanes" that contains one or more children of
-its own, each representing one of the lanes controlled by the pad.
-
-Required properties:
---------------------
-- status: Defines the operation status of the PHY. Valid values are:
- - "disabled": the PHY is disabled
- - "okay": the PHY is enabled
-- #phy-cells: Should be 0. Since each lane represents a single PHY, there is
- no need for an additional specifier.

-Port nodes:
-===========
-
-A required child node named "ports" contains a list of all the ports exposed
-by the XUSB pad controller. Per-port configuration is only required for USB.
-
-USB2 ports:
------------
-
-Required properties:
-- status: Defines the operation status of the port. Valid values are:
- - "disabled": the port is disabled
- - "okay": the port is enabled
-- mode: A string that determines the mode in which to run the port. Valid
- values are:
- - "host": for USB host mode
- - "device": for USB device mode
- - "otg": for USB OTG mode
-
-Required properties for OTG/Peripheral capable USB2 ports:
-- usb-role-switch: Boolean property to indicate that the port support OTG or
- peripheral mode. If present, the port supports switching between USB host
- and peripheral roles. Connector should be added as subnode.
- See usb/usb-conn-gpio.txt.
-
-Optional properties:
-- nvidia,internal: A boolean property whose presence determines that a port
- is internal. In the absence of this property the port is considered to be
- external.
-- vbus-supply: phandle to a regulator supplying the VBUS voltage.
-
-ULPI ports:
------------
-
-Optional properties:
-- status: Defines the operation status of the port. Valid values are:
- - "disabled": the port is disabled
- - "okay": the port is enabled
-- nvidia,internal: A boolean property whose presence determines that a port
