The code in this driver which parses the devicetree to determine the phy/fixed link setup, can be replaced by a single library function: of_phy_get_and_connect(). Behaviour is identical, except that the library function will complain when 'phy-connection-type' is omitted, instead of blindly using PHY_INTERFACE_MODE_NA, which would result in an invalid phy configuration. The library function no longer brings out the exact phy_mode, but the driver doesn't need this, because phy_interface_is_rgmii() queries the phydev directly. Remove 'phy_mode' from the private adapter struct. While we're here, log info about the attached phy on connect, this is useful because the phy type and connection method is now fully configurable via the devicetree. Tested on a lan7430 chip with built-in phy. Verified that adding fixed-link/phy-connection-type in the devicetree results in a fixed-link setup. Used ethtool to verify that the devicetree settings are used.

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.
