====================
net: bcmgenet: restore internal EPHY support (part 2)
This is a follow up to my previous submission (see [1]).
The first commit provides what is intended to be a complete solution
for the issues that can result from insufficient clocking of the MAC
during reset of its state machines. It should be backported to the
stable releases.
It is intended to replace the partial solution of commit 1f515486275a
("net: bcmgenet: soft reset 40nm EPHYs before MAC init") which is
reverted by the second commit of this series and should not be back-
ported as noted in [2].
The third commit corrects a timing hazard with a polled PHY that can
occur when the MAC resumes and also when a v3 internal EPHY is reset
by the change in commit 25382b991d25 ("net: bcmgenet: reset 40nm EPHY
on energy detect"). It is expected that commit 25382b991d25 be back-
ported to stable first before backporting this commit.

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.
