Subject[RFC PATCH v2 1/4] devicetree: hwmon: Add bindings for ADC128D818
Date
Add bindings documentation for the ADC128D818 driver, featuring default I2C
properties along with the optional 'mode' property for chip operation mode
selection (see datasheet, sec. 8.4.1).

+TI ADC128D818 ADC System Monitor With Temperature Sensor
+--------------------------------------------------------
+
+Operation modes:
+
+ - Mode 0: 7 single-ended voltage readings (IN0-IN6),
+ 1 temperature reading (internal)
+ - Mode 1: 8 single-ended voltage readings (IN0-IN7),
+ no temperature
+ - Mode 2: 4 pseudo-differential voltage readings
+ (IN0-IN1, IN3-IN2, IN4-IN5, IN7-IN6),
+ 1 temperature reading (internal)
+ - Mode 3: 4 single-ended voltage readings (IN0-IN3),
+ 2 pseudo-differential voltage readings
+ (IN4-IN5, IN7-IN6),
+ 1 temperature reading (internal)
+
+If no operation mode is configured via device tree, the driver defaults
+to Mode 0.
+
+
+Required node properties:
+
+ - compatible: must be set to "ti,adc128d818"
+ - reg: I2C address of the device
+
+Optional node properties:
+
+ - mode: Operation mode (see above).
+
+
+Example (operation mode 2):
+
+ adc128d818@1d {
+ compatible = "ti,adc128d818";
+ reg = <0x1d>;
+ mode = /bits/ 8 <2>;
+ };
