+Device tree binding for NVIDIA Tegra XUSB device mode controller (XUDC)
+=======================================================================
+
+The Tegra XUDC controller supports both USB 2.0 HighSpeed/FullSpeed and
+USB 3.0 SuperSpeed protocols.
+
+Required properties:
+--------------------
+- compatible: For Tegra210, must contain "nvidia,tegra210-xudc".
+- reg: Must contain the base and length of the XUSB device registers, XUSB device
+  PCI Config registers and XUSB device controller registers.
+- reg-names: Must include all the register names needed for the driver
+- interrupts: Must contain the XUSB device interrupt.
+- clocks: Must contain an entry for all clocks used.
+  See ../clock/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+   - dev: Clock to enable core XUSB dev clock.
+   - ss: Clock to enable XUSB super speed clock.
+   - ss_src: Clock to enable XUSB super speed dev clock.
+   - hs_src: Clock to enable XUSB high speed dev clock.
+   - fs_src: Clock to enable XUSB full speed dev clock.
+- nvidia,xusb-padctl: phandle to the XUSB pad controller that is used to
+  configure the USB pads used by the XUDC controller.
+- power-domains: A list of PM domain specifiers that reference each power-domain
+  used by the XUSB device mode controller. This list must comprise of a specifier
+  for the XUSBA and XUSBB power-domains. See ../power/power_domain.txt and
+  ../arm/tegra/nvidia,tegra20-pmc.txt for details.
+- power-domain-names: A list of names that represent each of the specifiers in
+  the 'power-domains' property. Must include 'ss' and 'dev'.
+- phys: Must contain an entry for each entry in phy-names.
+  See ../phy/phy-bindings.txt for details.
+- phy-names: Should include an entry for each PHY used by the controller.
+  Names must be "usb2", and "usb3" if support SuperSpeed device mode.
+  - "usb3" phy, SuperSpeed (SSTX+/SSTX-/SSRX+/SSRX-) data lines.
+  - "usb2" phy, USB 2.0 (D+/D-) data lines.
+
+For Tegra210:
+- avddio-usb-supply: PCIe/USB3 analog logic power supply. Must supply 1.05 V.
+- hvdd-usb-supply: USB controller power supply. Must supply 3.3 V.
+
+
+Optional properties:
+--------------------
+- usb-role-switch: boolean property to indicate use of USB Role Switch driver.
+
+Sub-nodes:
+----------
+- The port would be added as subnode if use "usb-role-switch" property.
