DT binding document for INA3221 iio/meter driver.
Required properties:
- compatible: Must be "ti,ina3221x".
- reg: I2C slave address of device.
- ti,trigger-config: Trigger configuration for the device in trigger mode.
- ti,continuous-config: Device configuration in continuous mode. In this mode
device will keep scanning the inputs.
- address-cells: Number of address in child node. Must be 1.
- size-cells: Size of address cell. Must be 0.
Optional sub-nodes:
Device has 3 input channels and channel specific information
is provided through the child node. Each channel will have different child
node. The channel number is identified by the reg properties on each of node.
Required subnode properties:
- reg: channel number. 0 for channel 0, 1 for channel 1 and 2 for channel 2.
- ti,rail-mae: Name of the channel in string.
Optional subnode properties:
- ti,current-warning-limit-ma: Cureent warning limit for the given channel.
- ti,current-critical-limit-ma: Current critical limit for the given channel.
- ti,shunt-resistor-mohm: Shunt register in milli ohm.
Example:
ina3221x@40 {
compatible = "ti,ina3221x";
reg = <0x40>;
ti,trigger-config = <0x7003>;
ti,continuous-config = <0x7c07>;
#address-cells = <1>;
#size-cells = <0>;
channel@0 {
reg = <0x0>;
ti,rail-name = "VDD_BAT";
ti,current-warning-limit-ma = <8000>;
ti,current-critical-limit-ma = <9000>;
ti,shunt-resistor-mohm = <1>;
};
channel@1 {
reg = <0x1>;
ti,rail-name = "VDD_CPU";
ti,shunt-resistor-mohm = <1>;
};
channel@2 {
reg = <0x2>;
ti,rail-name = "VDD_GPU";
ti,shunt-resistor-mohm = <1>;
};
};
