Linux kernel source tree
7ce11d4704
The ICSSGs on K3 J721E SoCs contain an MDIO controller that can be used to control external PHYs associated with the Industrial Ethernet peripherals within each ICSSG instance. The MDIO module used within the ICSSG is similar to the MDIO Controller used in TI Davinci SoCs. A bus frequency of 1 MHz is chosen for the MDIO operations. The nodes are added and enabled in the common k3-j721e-main.dtsi file by default, and disabled in the existing J721E board dts file. These nodes need pinctrl lines, and so should be enabled only on boards where they are actually wired and pinned out for ICSSG Ethernet. Any new board dts file should disable these if they are not sure.

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.
