Description
-----------
The TI / Burr-Brown INA209 monitors voltage, current, and power on the high side
of a D.C. power supply. It can perform measurements and calculations in the
background to supply readings at any time. It includes a programmable
calibration multiplier to scale the displayed current and power values.
Sysfs entries
-------------
The INA209 chip is highly configurable both via hardwiring and via
the I2C bus. See the datasheet for details.
This tries to expose most monitoring features of the hardware via
sysfs. It does not support every feature of this chip.

General Remarks
---------------
The power and current registers in this chip require that the calibration
register is programmed correctly before they are used. Normally this is expected
to be done in the BIOS. In the absence of BIOS programming, the shunt resistor
voltage can be provided using platform data. The driver uses platform data from
the ina2xx driver for this purpose. If calibration register data is not provided
via platform data, the driver checks if the calibration register has been
programmed (ie has a value not equal to zero). If so, this value is retained.
Otherwise, a default value reflecting a shunt resistor value of 10 mOhm is
programmed into the calibration register.
Output Pins
-----------
Output pin programming is a board feature which depends on the BIOS. It is
outside the scope of a hardware monitoring driver to enable or disable output
pins.
