commit221c3a09ddupstream. Fix the phy address to 7 for Ethernet PHY on SAMA5D27 SOM1. No connection established if phy address 0 is used. The board uses the 24 pins version of the KSZ8081RNA part, KSZ8081RNA pin 16 REFCLK as PHYAD bit [2] has weak internal pull-down. But at reset, connected to PD09 of the MPU it's connected with an internal pull-up forming PHYAD[2:0] = 7.

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.
