1Texas Instruments INA3221 Device Tree Bindings
2
31) ina3221 node
4  Required properties:
5  - compatible: Must be "ti,ina3221"
6  - reg: I2C address
7
8  Optional properties:
9  - ti,single-shot: This chip has two power modes: single-shot (chip takes one
10                    measurement and then shuts itself down) and continuous (
11                    chip takes continuous measurements). The continuous mode is
12                    more reliable and suitable for hardware monitor type device,
13                    but the single-shot mode is more power-friendly and useful
14                    for battery-powered device which cares power consumptions
15                    while still needs some measurements occasionally.
16                    If this property is present, the single-shot mode will be
17                    used, instead of the default continuous one for monitoring.
18
19  = The node contains optional child nodes for three channels =
20  = Each child node describes the information of input source =
21
22  - #address-cells: Required only if a child node is present. Must be 1.
23  - #size-cells: Required only if a child node is present. Must be 0.

252) child nodes
26  Required properties:
27  - reg: Must be 0, 1 or 2, corresponding to IN1, IN2 or IN3 port of INA3221
28
29  Optional properties:
30  - label: Name of the input source
31  - shunt-resistor-micro-ohms: Shunt resistor value in micro-Ohm
