2023-10-28dt-bindings: hwmon: ina3221: Add ti,summation-disableJon Hunter1-0/+19
The INA3221 has a critical alert pin that can be controlled by the summation control function. This function adds the single shunt-voltage conversions for the desired channels in order to compare the combined sum to the programmed limit. The Shunt-Voltage Sum Limit register contains the programmed value that is compared to the value in the Shunt-Voltage Sum register in order to determine if the total summed limit is exceeded. If the shunt-voltage sum limit value is exceeded, the critical alert pin pulls low. For the summation limit to have a meaningful value, it is necessary to use the same shunt-resistor value on all included channels. Add a new vendor specific property, 'ti,summation-disable', to allow specific channels to be excluded from the summation control function if the shunt resistor is different to other channels or the channel should not be considered for triggering the critical alert pin. Note that the ina3221 has always supported summing the various input channels and summation is enabled by default if the shunt-resistor values are the same. This change simply provides a way to exclude inputs from the summation. If this property is not populated, then the functionality of the driver does not change.

Convert the TI INA3221 bindings from the free-form text format to json-schema. Note that the INA3221 input channels default to enabled in the chip. Unless channels are explicitly disabled in device-tree, input channels will be enabled.

These modify the corresponding bits in the configuration register. adi,comp-int is a hardware property, because it affects the behavior of the interrupt signal and whatever it is connected to. adi,timeout-enable is a hardware property, because it affects i2c bus operation.
