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 INA231 is a high or low side current shunt and power monitor with an I2C

interface. The INA231 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.
