This binding is fairly bare-bones for now, since the Lynx driver doesn't
parse any properties (or match based on the compatible). We just need it
in order to prevent the PCS nodes from having phy devices attached to
them. This is not really a problem, but it is a bit inefficient.
This binding is really for three separate PCSs (SGMII, QSGMII, and XFI).
However, the driver treats all of them the same. This works because the
SGMII and XFI devices typically use the same address, and the SerDes
driver (or RCW) muxes between them. The QSGMII PCSs have the same
register layout as the SGMII PCSs. To do things properly, we'd probably
do something like
ethernet-pcs@0 {
#pcs-cells = <1>;
compatible = "fsl,lynx-pcs";
reg = <0>, <1>, <2>, <3>;
};
but that would add complexity, and we can describe the hardware just
fine using separate PCSs for now.

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.
