Frank Rowand cf03712622 of: overlay: use prop add changeset entry for property in new nodes 
commit 6b4955ba7b upstream.

The changeset entry 'update property' was used for new properties in
an overlay instead of 'add property'.

The decision of whether to use 'update property' was based on whether
the property already exists in the subtree where the node is being
spliced into.  At the top level of creating a changeset describing the
overlay, the target node is in the live devicetree, so checking whether
the property exists in the target node returns the correct result.
As soon as the changeset creation algorithm recurses into a new node,
the target is no longer in the live devicetree, but is instead in the
detached overlay tree, thus all properties are incorrectly found to
already exist in the target.

This fix will expose another devicetree bug that will be fixed
in the following patch in the series.

When this patch is applied the errors reported by the devictree
unittest will change, and the unittest results will change from:

   ### dt-test ### end of unittest - 210 passed, 0 failed

to

   ### dt-test ### end of unittest - 203 passed, 7 failed

README 

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.
