Registering our slave MDIO bus outside of the OF infrastructure is
necessary in order to avoid creating double references of the same
Device Tree nodes, however it is not sufficient to guarantee that the
MDIO bus diversion is used because of_phy_connect() will still resolve
to a valid PHY phandle and it will connect to the PHY using its parent
MDIO bus which is still the SF2 master MDIO bus. The reason for that is
because BCM7445 systems were already shipped with a Device Tree blob
looking like this (irrelevant parts omitted for simplicity):
ports {
#address-cells = <1>;
#size-cells = <0>;
port@1 {
phy-mode = "rgmii-txid";
phy-handle = <&phy0>;
reg = <1>;
label = "rgmii_1";
};
...
mdio@403c0 {
...
phy0: ethernet-phy@0 {
broken-turn-around;
device_type = "ethernet-phy";
max-speed = <0x3e8>;
reg = <0>;
compatible = "brcm,bcm53125", "ethernet-phy-ieee802.3-c22";
};
};
There is a hardware issue with chip revisions (Dx) that lead to the

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.
