Linux kernel source tree
2c60c4c008
The driver used the DT node of the device itself when registering the MDIO bus. While this works, it creates a problem: it forces any MDIO bus properties to also be set on the devices DT node. This mixes the properties of two distinctly different things and is confusing. This change adds support for an optional mdio node to be defined as a child to the device DT node. The child node can then be used to describe MDIO bus properties that the MDIO core can act on when registering the bus. If no mdio child node is found the driver fallback to the old behavior and register the MDIO bus using the device DT node. This change is backward compatible with old bindings in use.

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 reStructuredText 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.
