Making gpio8 and gpio9 vendor specific and putting them into the specific dts file makes not needed to release gpios anymore because we are not occupying those pins in the first place if it is not necessary. When the device tree is parsed we can also check and return for the error because we rely in the fact that the related device for the board is correct.

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.
