+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
