The generic ethernet-phy binding allows describing an external clock since
commit 350b7a258f ("dt-bindings: net: phy: Document support for external PHY clk")
for cases where the phy is not supplied by an oscillator but instead
by a clock from the host system.
And the old named "rmii-ref" clock from 2014 is only specified for phys
of the KSZ8021, KSZ8031, KSZ8081, KSZ8091 types.
So allow retrieving and enabling the optional generic clock on phys that
do not provide a rmii-ref clock.

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.
