[ Upstream commit c04a17d2a9 ]
We are binding to the PHY using the SF2 slave MDIO bus that we create,
binding involves reading the PHY's MII_PHYSID1/2 which won't be possible
if the PHY is turned off. Temporarily turn it on/off for the bus probing
to succeeed. This fixes unbind/bind problems where the port connecting
to that PHY would be in error since it could not connect to it.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
