There is a current sensing circuitry on the phyBOARD-Nash-i.MX93 capable of measuring input current consumption of the phyCORE-i.MX93 SoM @ 3.3V. Circuity consists of MAX4372 current-sense amplifier (50V/V) with two 70 mOhm shunts resistors in parallel configuration (effective R = 35 mOhm) connected to the SoC internal 12-bit ADC channel #1 (Vref = 1.8V) via voltage divider with ratio of 1/2. This results in a current scaling factor of 0.502232142 mA/LSB. Signed-off-by: Primoz Fiser <primoz.fiser@norik.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
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 reStructuredText 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.
