Stefano Radaelli fe71b71f0f net: phy: mxl-86110: Add power management and soft reset support 
[ Upstream commit 62f7edd599 ]

Implement soft_reset, suspend, and resume callbacks using
genphy_soft_reset(), genphy_suspend(), and genphy_resume()
to fix PHY initialization and power management issues.

The soft_reset callback is needed to properly recover the PHY after an
ifconfig down/up cycle. Without it, the PHY can remain in power-down
state, causing MDIO register access failures during config_init().
The soft reset ensures the PHY is operational before configuration.

The suspend/resume callbacks enable proper power management during
system suspend/resume cycles.

README 

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 reStructuredText 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.
