+Required properties:
+       - compatible: must be "ti,twl6030-gpadc" for TWL6030 or
+         "ti,twl6032-gpadc" for TWL6032
+       - interrupts: interrupt number associated with it
+       - #io-channel-cells: must be <1> - multiple IIO outputs
+
+Example:
+       adc {
+               compatible = "ti,twl6030-gpadc";
+               interrupts = <3>;
+               #io-channel-cells = <1>;
