The only user of fixed_phy gpio functionality was here: arch/arm/boot/dts/nxp/vf/vf610-zii-dev-rev-b.dts Support for the switch on this board was migrated to phylink (DSA - mv88e6xxx) years ago, so the functionality is unused now. Therefore remove it. Note: There is a very small risk that there's out-of-tree users who use link gpio with a switch chip not handled by DSA. However we care about in-tree device trees only.

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.
