J. Neuschäfer b33f8cfb2b arm64: dts: amlogic: Add Ugoos AM3
The Ugoos AM3 is a small set-top box based on the Amlogic S912 SoC,
with a board design that is very close to the Q20x development boards.
The MMC max-frequency properties are copied from the downstream device
tree.

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.
