Add ethernet refclock mux support and set it to internal clock by
default. This configuration will not affect existing boards.
clock tree before this patch:
fec1 <- enet1_ref_125m (gate) <- enet1_ref (divider) <-,
|- pll6_enet
fec2 <- enet2_ref_125m (gate) <- enet2_ref (divider) <-´
after this patch:
fec1 <- enet1_ref_sel(mux) <- enet1_ref_125m (gate) <- ...
`--<> enet1_ref_pad |- pll6_enet
fec2 <- enet2_ref_sel(mux) <- enet2_ref_125m (gate) <- ...

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.
