If there is no specific configuration of the felix switch in the device tree, but only the default configuration (ie. given by the SoCs dtsi file), the probe fails because no CPU port has been set. On the other hand you cannot set a default CPU port because that depends on the actual board using the switch. [ 2.701300] DSA: tree 0 has no CPU port [ 2.705167] mscc_felix 0000:00:00.5: Failed to register DSA switch: -22 [ 2.711844] mscc_felix: probe of 0000:00:00.5 failed with error -22 Thus let the device tree disable this device entirely, like it is also done with the enetc driver of the same SoC.

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.
