| Description |
| ----------- |
| |
| The INA219 is a high-side current shunt and power monitor with an I2C |
| interface. The INA219 monitors both shunt drop and supply voltage, with |
| programmable conversion times and filtering. |
| |
| The INA220 is a high or low side current shunt and power monitor with an I2C |
| interface. The INA220 monitors both shunt drop and supply voltage. |
| |
| The INA226 is a current shunt and power monitor with an I2C interface. |
| The INA226 monitors both a shunt voltage drop and bus supply voltage. |
| |
| The INA230 is a high or low side current shunt and power monitor with an I2C |
| interface. The INA230 monitors both a shunt voltage drop and bus supply voltage. |
| |
| The shunt value in micro-ohms can be set via platform data or device tree. |
| Please refer to the Documentation/devicetree/bindings/i2c/ina2xx.txt for bindings |
| if the device tree is used. |
