This patch will allow to use a swnode/fwnode defined for a phy_device. The MDIO bus (mii_bus) needs to contain nodes for the PHY devices, named "ethernet-phy@i", with i being the MDIO address (0 .. PHY_MAX_ADDR - 1). The fwnode is only attached to the phy_device if there isn't already an fwnode attached. fwnode_get_named_child_node will increase the usage counter of the fwnode. However, no new code is needed to decrease the counter again, since this is already implemented in the phy_device_release function.

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.
