- diff-channels : Differential channels muxed for this ADC. The first value
specifies the positive input pin, the second value the negative
input pin.
+- reg: The channel number.
+- label: Unique name to identify which channel this is.

Example:
adc@0 {

channel@0 {

+ label = "channel_0_name";
bipolar;
diff-channels = <0 1>;
