[ Upstream commit edfea889a049abe80f0d55c0365bf60fbade272f ] The PHY reset line is connected to both the SoC (GPIO1_25) and the CPLD. We must not use the GPIO1_25 as it will drive against the output buffer of the CPLD. Instead there is another GPIO (GPIO2_01), an input to the CPLD, which will tell the CPLD to assert the PHY reset line.

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.
