From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
Each driver that uses this will need to use a $ref
We can't always enable it like most of the generic bindings due to
channel@X matching far more widely than IIO.

-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>;
- ...
- };

+ description:
+ Many ADCs have dual Muxes to allow different input pins to be routed

+ The first value specifies the positive input pin, the second
