Document the FS Differential TX Output Resistance Tuning value found on the eUSB2 repeater on Qualcomm PMICs. The tuning values have special meanings, being different offsets of the resistance to the default value in Ohms but the exact meaning is not relevant here, as the correct tuning is determined by hardware engineers to make sure the electrical properties are as expected.

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.
