In april 2007, ucc_geth was converted to phylib with : commit728de4c927("ucc_geth: migrate ucc_geth to phylib"). In that commit, the device-tree property "interface", that could be used to retrieve the PHY interface mode was deprecated. DTS files that still used that property were converted along the way, in the following commit, also dating from april 2007 : commit0fd8c47ccc("[POWERPC] Replace undocumented interface properties in dts files") 17 years later, there's no users of that property left and I hope it's safe to say we can remove support from that in the ucc_geth driver, making the probe() function a bit simpler. Should there be any users that have a DT that was generated when 2.6.21 was cutting-edge, print an error message with hints on how to convert the devicetree if the 'interface' property is found. With that property gone, we can greatly simplify the parsing of the phy-interface-mode from the devicetree by using of_get_phy_mode(), allowing the removal of the open-coded parsing in the driver.

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.
