To me it seems that you can leave out all the above. You can set these falgs
flags directly in the driver based on the compatible flag. Then just initialize
the .data in the driver based on the compatible flag.

Then you would instead have something like this:

	compatible = "ti,am347-control-phy-otghs";

That way you can initialize things without a need for custom bindings.
