On TypeC ports if a sink deasserts/reasserts its HPD signal, generating a hotplug interrupt without the sink getting unplugged/replugged from the connector, there can be an up to 3 seconds delay until the AUX channel gets functional. To avoid detection failures this delay causes retry the detection for 5 seconds. I noticed this on ICL/TGL RVPs and a DELL XPS 13 7390 ICL laptop.

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.
