Make MDIO child optional and only instantiate the MDIO bus if the child is actually present. There are currently no (in-tree) users of this binding; all (out-of-tree) users use overlays that get shipped together with the FPGA images that contain the IP. This will significantly increase maintainabilty of future revisions of this IP. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: David S.

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.
