At reset, KSZ8463 uses a strap-based configuration to set SPI as interface bus. If the required pull-ups/pull-downs are missing (by mistake or by design to save power) the pins may float and the configuration can go wrong preventing any communication with the switch. Add a 'reset' pinmux state Add a KSZ8463 specific strap description that can be used by the driver to drive the strap pins during reset. Two GPIOs are used. Users must describe either both of them or none of them.

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.
