3	OMAP USB2 PHY
4	
5	Required properties:
6	 - compatible: Should be "ti,omap-usb2"
7	 - reg : Address and length of the register set for the device.
8	 - #phy-cells: determine the number of cells that should be given in the
9	   phandle while referencing this phy.
10	
11	Optional properties:
12	 - ctrl-module : phandle of the control module used by PHY driver to power on
13	   the PHY.
