+Tegra SOC USB PHY
+
+The device node for Tegra SOC USB PHY:
+
+Required properties :
+ - compatible : Should be "nvidia,tegra20-usb-phy".
+ - reg : Address and length of the register set for the USB PHY interface.
+ - phy_type : Should be one of "ulpi" or "utmi".
+
+Required properties for phy_type == ulpi:
+ - nvidia,phy-reset-gpio : The GPIO used to reset the PHY.
+
+Optional properties:
+ - nvidia,has-legacy-mode : boolean indicates whether this controller can
+ operate in legacy mode (as APX 2500 / 2600). In legacy mode some
+ registers are accessed through the APB_MISC base address instead of
+ the USB controller. \ No newline at end of file
