mainlining shenanigans
dbdcc22c84
Tegra PCIe has fixed per port SFIO line to signal PERST#, which can be controlled by AFI port register. However, if a platform routes a different GPIO to the PCIe slot, then port register cannot control it. Add support for GPIO based PERST# signal for such platforms. GPIO number comes from per port PCIe device tree node. PCIe driver probe doesn't fail if per port "reset-gpios" property is not populated, so platforms that require this workaround must make sure that the DT property is not missed in the corresponding device tree.

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.
