-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.
-- reg: The channel number.
-- label: Unique name to identify which channel this is.
-
-Example:
- adc@0 {
- compatible = "some,adc";
- ...
- channel@0 {
- reg = <0>;
- label = "channel_0_name";
- bipolar;
- diff-channels = <0 1>;
- ...
- };
-
- channel@1 {
- reg = <1>;
- label = "channel_1_name";
- diff-channels = <2 3>;
- ...
- };
- };
