This patch adds support for specifying system controller that configures
phy-mode setting.
According to the DT property "phy-mode", it's necessary to configure the
controller, which is used to choose the settings of the MAC suitable,
for example, mdio pin connections, internal clocks, and so on.
Supported phy-modes are SoC-dependent. The driver allows phy-mode to set
"internal" if the SoC has a built-in PHY, and {"mii", "rmii", "rgmii"}
if the SoC supports each mode. So we have to check whether the phy-mode
is valid or not.
This adds the following features for each SoC:
- check whether the SoC supports the specified phy-mode
- configure the controller accroding to phy-mode
The DT property accepts one argument to distinguish them for multiple MAC
instances.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
