-- ti,differential-input
-  Set to use the device in differential mode.
-- vref-supply
-  The external reference on the device is set to this regulators output. If it
-  does not exists the internal reference will be used and output by the ads78xx
-  on the "external vref" pin.

-	   reg = <0x48>;
-	   vref-supply = <&vref>;
