When connected to a micrel phy, phy_find_first doesn't work properly because the first phy found is on address 0, the broadcast address but, the first thing the phy driver is doing is disabling this broadcast address. The phy is then available only on address 1 but the mdio driver doesn't know about it. Instead, register the mdio bus using of_mdiobus_register and try to find the phy description in device tree before falling back to phy_find_first. This ultimately also allows to describe the interrupt the phy is connected to.

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.
