commitc4d1ca05b8upstream. The xHCI controller on Alpine Ridge LP keeps the whole Thunderbolt controller awake if the host controller is not allowed to sleep. This is the case even if no USB devices are connected to the host. Add the Intel Alpine Ridge LP product-id to the list of product-ids for which we allow runtime PM by default.

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.
