Add bindings for SolidRun boards based on CN9130 SoM. Three boards are added in total: - Clearfog Base - Clearfog Pro - SolidWAN The Clearfog boards are identical to the older Armada 388 based boards, upgraded with a new SoM and SoC. However the feature set and performance characteristics are different, therefore compatible strings from armada 388 versions are not included. SolidWAN uses the same SoM adding a southbridge on the carrier. Since 2019 there are bindings in-tree for two boards based on cn9130 and 9131. These are extremely verbose by listing cn9132, cn9131, cn9130, ap807-quad, ap807 for the SoC alone. CN9130 SoC combines an application processor (ap807) and a communication processor (cp115) in a single package. The communication processor (short CP) is also available separately as a southbridge. It only functions in combination with the CN9130 SoC. Complete systems adding one or two southbridges are by convention called CN9131 and CN9132 respectively. Despite different naming all systems are built around the same SoC. Therefore marvell,cn9131 and marvell,cn9132 can be omitted. The number of CPs is part of a board's BoM and can be reflected in the board compatible string instead. Existing bindings also describe cn9130 as a specialisation of ap807-quad. Usually board-level compatibles stop at the SoC without going into silicon versions or individual dies. There is no programming model at this layer, and in particular not for parts of an SoC. Therefore the ap compatibles can also be omitted.

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.
