The ocelot switch driver used to ignore ports which do not have a phy-handle property and not probe those, but this is not quite ok since it is valid to not have a phy-handle property if there is a fixed-link. It seems that checking for a phy-handle was a proxy for the proper check which is for the status, but that doesn't make a lot of sense, since the ocelot driver already iterates using for_each_available_child_of_node which skips the disabled ports, so I have no idea. Anyway, a widespread pattern in device trees is for a SoC dtsi to disable by default all hardware, and let board dts files enable what is used. So let's do that and enable only the ports with a phy-handle in the pcb120 and pcb123 device tree files.

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.
