This patch largely replicates Vivek Unune's patch "ARM: dts: BCM5301X:Make usb3 phy use mdio phy driver"[1] for the NSP platform, whereby we need to create an mdio-mux to facilitate switches configured via external MDIO, in this case on the Meraki MX65. However in doing so, we are creating an overlap with usb3_phy's ccb-mii range. To resolve this, usb3_phy should be moved to a child node of the internal MDIO bus. The result is heavily based upon Vivek's patch. This has also been cross-referenced with Yendapally Reddy's earlier work which utilised the subsequently dropped brcm,nsp-usb3-phy driver: "[PATCH v2 4/4] arm: dts: nsp: Add USB nodes to device tree" [2]. Finally, this change provides conformance to the bcm-ns-usb3-phy documentation, utilising the required usb3-dmp-syscon property. Note that support for the deprecated ccb-mii bindings has been dropped as of "phy: phy-bcm-ns-usb3: drop support for deprecated DT binding"[3].

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.
