On older Apple systems there is currently a PCI quirk in place to block resume of tunneled PCIe ports until NHI (Thunderbolt controller) is resumed. This makes sure the PCIe tunnels are re-established before PCI core notices it. With device links the same thing can be done without quirks. The driver core will make sure the supplier (NHI) is resumed before consumers (PCIe downstream ports). For this reason switch the Thunderbolt driver to use device links and remove the PCI quirk.

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.
