+Common ADCs properties
+
+Optional properties for child nodes:
+- bipolar : Boolean, if set the channel is used in bipolar mode.
+- diff-channels : Differential channels muxed for this ADC. The first value
+		specifies the positive input pin, the second value the negative
+		input pin.
+
+Example:
+	adc@0 {
+		compatible = "some,adc";
+		...
+		channel@0 {
+			bipolar;
+			diff-channels = <0 1>;
+			...
+		};
+
+		channel@1 {
+			diff-channels = <2 3>;
+			...
+		};
+	};
