Texas Instruments INA3221 Device Tree Bindings
1) ina3221 node
Required properties:
- compatible: Must be "ti,ina3221"
- reg: I2C address
Optional properties:
= The node contains optional child nodes for three channels =
= Each child node describes the information of input source =
- #address-cells: Required only if a child node is present. Must be 1.
- #size-cells: Required only if a child node is present. Must be 0.
2) child nodes
Required properties:
- reg: Must be 0, 1 or 2, corresponding to IN1, IN2 or IN3 port of INA3221
Optional properties:
- label: Name of the input source
- shunt-resistor-micro-ohms: Shunt resistor value in micro-Ohm
Example:
ina3221@40 {
compatible = "ti,ina3221";
reg = <0x40>;
#address-cells = <1>;
#size-cells = <0>;
input@0 {
reg = <0x0>;
status = "disabled";
};
input@1 {
reg = <0x1>;
shunt-resistor-micro-ohms = <5000>;
};
input@2 {
reg = <0x2>;
label = "VDD_5V";
shunt-resistor-micro-ohms = <5000>;
};
};
