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 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.
