    Subject[PATCH v2 1/2] dt-bindings: hwmon: Add ina3221 documentation
    Date
    Texas Instruments INA3221 is a triple-channel shunt and bus
    voltage monitor. This patch adds a DT binding doc for it.

    Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com>

    Changelog
    v1->v2:
    * Dropped channel name properties
    * Added child node definitions.
    * * Added shunt resistor property in the child node
    * * Added status property to indicate connection status
    * * Changed to use child node name as the label of input source

    +ina3221 properties
    +
    +1) ina3221 node
    + Required properties:
    + - compatible: Must be "ti,ina3221"
    + - reg: I2C address
    +
    + = The node contains optional child nodes for three channels =
    + = Each child node describes the information of input source =
    +
    + Example:
    +
    + ina3221@40 {
    + compatible = "ti,ina3221";
    + reg = <0x40>;
    + [ child node definitions... ]
    + };
    +
    +2) child nodes
    + The names of child nodes should indicate input source names
    +
    + Required properties:
    + - input-id: Must be 1, 2 or 3
    +
    + Optional properties:
    + - shunt-resistor: Shunt resistor value in micro-Ohm
    + - status: Should be "disabled" if no input source
    +
    + Example:
    +
    + input1 {
    + input-id = <0x1>;
    + status = "disabled";
    + };
    + VDD_GPU {
    + input-id = <0x2>;
    + shunt-resistor = <5>;
    + };
