The DP83869 PHY on TI's k3-am642-evm supports both MII and RGMII interfaces and is configured by default to use RGMII interface (strap). However, the board design allows switching dynamically to MII interface for testing purposes by applying different set of pinmuxes. To support switching to MII interface, update the DP83869 PHY driver to configure OP_MODE_DECODE.RGMII_MII_SEL(bit 5) properly when MII PHY interface mode is requested.

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.
