There are devices in the wild with non-updatable firmware coming with ACPI tables with rejected compatibles, e.g. "ltr,ltrf216a". Linux kernel still supports this device via ACPI PRP0001, however the compatible was never accepted to bindings. There are also several early PowerPC or SPARC platforms using compatibles for their OpenFirmware, but without in-tree DTS. Often the legacy compatible is not correct in terms of current Devicetree specification, e.g. missing vendor prefix. Finally there are also Linux-specific tools and test code with compatibles. Add a schema covering above cases purely to satisfy the DT schema and scripts/checkpatch.pl checks for undocumented compatibles. For ltr,ltrf216a this also documents the consensus: compatible is allowed only via ACPI PRP0001, but not bindings.

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 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.
