-OMAP USB2 PHY
-
-Required properties:
- - compatible: Should be "ti,omap-usb2"
-	       Should be "ti,dra7x-usb2" for the 1st instance of USB2 PHY on
-	       DRA7x
-	       Should be "ti,dra7x-usb2-phy2" for the 2nd instance of USB2 PHY
-	       in DRA7x
-	       Should be "ti,am654-usb2" for the USB2 PHYs on AM654.
- - reg : Address and length of the register set for the device.
- - #phy-cells: determine the number of cells that should be given in the
-   phandle while referencing this phy.
- - clocks: a list of phandles and clock-specifier pairs, one for each entry in
-   clock-names.
- - clock-names: should include:
-   * "wkupclk" - wakeup clock.
-   * "refclk" - reference clock (optional).
-
-Deprecated properties:
- - ctrl-module : phandle of the control module used by PHY driver to power on
-   the PHY.
-
-Recommended properies:
-- syscon-phy-power : phandle/offset pair. Phandle to the system control
-  module and the register offset to power on/off the PHY.
-
-This is usually a subnode of ocp2scp to which it is connected.
