PHY configuration has been implemented in the firmware and accessed through SMC calls. In the past, it worked magically if the bootloader was correctly doing the initializations. With up-to-date bindings, the kernel will need a recent firmware in order to do the initializations himself (we assume people must update their firmware along with their kernel). People might not understand why IPs that were working correctly before stopped to be probed suddendly. In this case, let's advise the users to update their firmware with a visual warning.

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.
