The PRUSS on AM335x SoCs has a MDIO sub-module that can be used to control external PHYs associated with the Industrial Ethernet peripherals within the PRUSS. The MDIO module used within the PRU-ICSS is an instance of the MDIO Controller used in TI Davinci SoCs. The same bus frequency of 1 MHz is chosen as the regular MDIO node. The node is added to the common am33xx-l4.dtsi file and is disabled. This needs to be enabled in the respective board files using the relevant AM335x SoCs supporting PRUSS and where the ethernet is pinned out and connected properly.

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.
