[ Upstream commit ef2d90708883f4025a801feb0ba8411a7a4387e1 ]
Per KSZ9031RNX PHY datasheet FIGURE 7-5: POWER-UP/POWER-DOWN/RESET TIMING
Note 2: After the de-assertion of reset, wait a minimum of 100 μs before
starting programming on the MIIM (MDC/MDIO) interface.
Add 1ms post-reset delay to guarantee this figure.

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.
