Christophe Roullier 1bb694e208 net: ethernet: stmmac: simplify phy modes management for stm32 
No new feature, just to simplify stm32 part to be easier to use.
Add by default all Ethernet clocks in DT, and activate or not in function
of phy mode, clock frequency, if property "st,ext-phyclk" is set or not.
Keep backward compatibility

README 

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.
