When PCIe port is runtime suspended/resumed some extra steps might be
needed to be executed from the port service driver side. For instance we
may need to disable PCIe hotplug interrupt to prevent it from triggering
immediately when PCIe link to the downstream component goes down.
To make the above possible add optional ->runtime_suspend() and
->runtime_resume() callbacks to struct pcie_port_service_driver and call
them for each port service in runtime suspend/resume callbacks of portdrv.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
