The INA237 "85-V, 16-Bit, Precision Power Monitor With I2C Interface" is basically the same as INA328. Therefore add a corresponding compatible to the driver. According to the datasheet the main difference is the current and power monitoring accuracy: +------------------------+---------------+---------------+ | | INA238 | INA237 | +------------------------+---------------+---------------+ | Offset voltage | +/- 5µV | +/- 50µV | | Offset drift | +/- 0.02µV/°C | +/- 0.02µV/°C | | Gain error | +/- 0.1% | +/- 0.3% | | Gain error drift | +/- 25ppm/°C | +/- 50ppm/°C | | Common mode rejection | 140dB | 120dB | | Power accuracy | 0.7% | 1.6% | +------------------------+---------------+---------------+ As well as the missing DEVICE_ID register at 0x3F, which is currently not in use by the driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
