1TI ADC128D818 ADC System Monitor With Temperature Sensor
2--------------------------------------------------------
3
4Operation modes:
5
6 - Mode 0: 7 single-ended voltage readings (IN0-IN6),
7 1 temperature reading (internal)
8 - Mode 1: 8 single-ended voltage readings (IN0-IN7),
9 no temperature
10 - Mode 2: 4 pseudo-differential voltage readings
11 (IN0-IN1, IN3-IN2, IN4-IN5, IN7-IN6),
12 1 temperature reading (internal)
13 - Mode 3: 4 single-ended voltage readings (IN0-IN3),
14 2 pseudo-differential voltage readings
15 (IN4-IN5, IN7-IN6),
16 1 temperature reading (internal)
17
18If no operation mode is configured via device tree, the driver keeps the
19currently active chip operation mode (default is mode 0).

22Required node properties:
23
24 - compatible: must be set to "ti,adc128d818"
25 - reg: I2C address of the device
26
27Optional node properties:
28
29 - ti,mode: Operation mode (u8) (see above).

31
32Example (operation mode 2):
33
34 adc128d818@1d {
35 compatible = "ti,adc128d818";
36 reg = <0x1d>;
37 ti,mode = /bits/ 8 <2>;
38 };
