Subject[PATCH v4 2/4] dt-bindings: iio: adc: Add common ADCs properties to a separate file
Date
There are several ADC drivers that depend on the same device tree
bindings. Rather than continue to duplicate the properties, this patch
adds a common adc binding document that can be referenced. For beginning,
only two properties are documented.

+Common ADCs properties
+
+This binding is a work-in-progress
+
+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>;
+ ...
+ };
+ };
