DP83826 offers the possibility to tune the voltage of logical levels of the MLT-3 encoded TX data. This is useful when there is a voltage drop in between the PHY and the connector and we want to increase the voltage levels to compensate for that drop. Prior to PHY configuration, the driver SW resets the PHY which has the same effect as the HW reset pin according to the datasheet. Hence, there's no need to force update the VOD_CFG registers to make sure they hold their reset values. VOD_CFG registers need to be updated only if the DT has been configured with values other than the reset ones.

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.
