To provide backward compatibility for boards that use deprecated DT
bindings, we need to add fw_devlink support for "gpio" and "gpios".
We also need to ignore these properties on nodes with "gpio-hog"
property because their gpio[s] are all supplied by the parent node.
Fixes: e590474768 ("driver core: Set fw_devlink=on 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.
