That property is no used in mainline and is not documented. The only board using that property is the rk33-99-evb-rev1 and -rev2 in the vendor kernel. The existence of a further -rev3 (which also looks way better cared for compared rev1+2) indicates that the older ones are probably some sort of preproduction models, where some wiring (on the soc or board) may have gone wrong. It is also not clear why this is a hardware-description or a DT property, so, as noboby seems to care of this just drop reading that property.

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.
