The ON Semiconductor FSA4480 is a USB Type-C port multimedia switch with support for analog audio headsets. It allows sharing a common USB Type-C port to pass USB2.0 signal, analog audio, sideband use wires and analog microphone signal. Due to lacking upstream audio support for testing, the audio muxing is left untouched, but implementation of muxing the SBU lines is provided as a pair of Type-C mux and switch devices. This provides the necessary support for enabling the DisplayPort altmode on devices with this circuit.

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.
