GPIO machine lookup is a nice mechanism for associating GPIOs with consumers if we don't know what kind of device the GPIO provider is or when it will become available. However in the case of the reset-gpio, we are already holding a reference to the device and so can reference its firmware node. Let's setup a software node that references the relevant GPIO and attach it to the auxiliary device we're creating.

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 reStructuredText 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.
