  32-----------
  33
  34The INA219 is a high-side current shunt and power monitor with an I2C
  35interface. The INA219 monitors both shunt drop and supply voltage, with
  36programmable conversion times and filtering.
  37
  38The INA220 is a high or low side current shunt and power monitor with an I2C
  39interface. The INA220 monitors both shunt drop and supply voltage.
  40
  41The INA226 is a current shunt and power monitor with an I2C interface.
  42The INA226 monitors both a shunt voltage drop and bus supply voltage.
  43
  44The INA230 is a high or low side current shunt and power monitor with an I2C
  45interface. The INA230 monitors both a shunt voltage drop and bus supply voltage.
  46
  47The shunt value in micro-ohms can be set via platform data or device tree.
  48Please refer to the Documentation/devicetree/bindings/i2c/ina2xx.txt for bindings
  49if the device tree is used.
