The FSA4480 Type-C switch supports switching the Audio R/L, AGND and MIC signals to the USB-C DP/DM and SBU1/2 to support the Audio Accessory Mode. The FSA4480 has an integrated Audio jack detection mechanism to automatically mux the AGND, MIX and Sense to the correct SBU lines to support 3 pole and both 4 pole TRRS pinouts.

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.
