The ADM series of hotswap controllers support extending the current measurement range by using a sensing resistor value other than the typical 1 mOhm. For example, using a 0.5 mOhm sensing resistor doubles the maximal current can be measured. Current driver assumes a shunt resistor value of 1 mOhm in calculation, meaning for other resistor values, hwmon will report scaled current/power measurements. This patch parses device tree parameter "shunt-resistor-micro-ohms", if there is one. Signed-off-by: Kun Yi <kunyi@google.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
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.
