In the Type-C graph, the ptn36502 retimer is in between the USB-C connector and the USB3/DP combo PHY, and this PHY also requires the USB-C mode events to properly set-up the SuperSpeed Lanes functions to setup USB3-only, USB3 + DP Altmode or DP Altmode only on the 4 lanes. Update the ptn36502 retimer to get an optional type-c mux on the next endpoint, and broadcast the received mode to it.

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.
