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
|
|
|
|
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>;
|
|
...
|
|
};
|
|
};
