+Devicetree bindings schema checks
+---------------------------------

+With devicetee-rebasing Git subtree, the devicetree bindings are also regularly

+Dependencies
+~~~~~~~~~~~~
+
+The DT schema project must be installed in order to validate the DT schema
+binding documents and validate DTS files using the DT schema. The DT schema
+project can be installed with pip::
+
+    pip3 install dtschema
+
+Note that 'dtschema' installation requires 'swig' and Python development files
+installed first. On Debian/Ubuntu systems::
+
+    apt install swig python3-dev
+
+Several executables (dt-doc-validate, dt-mk-schema, dt-validate) will be
+installed. Ensure they are in your PATH (~/.local/bin by default).
+
+Recommended is also to install yamllint (used by dtschema when present).
+
+Running checks
+~~~~~~~~~~~~~~
+
+In order to perform validation of DTB files, use the ``dtbs_check`` target::
+
+    make dtbs_check
+
+It is also possible to run checks with a subset of matching schema files by
+setting the ``DT_SCHEMA_FILES`` variable to 1 or more specific schema files or
+patterns (partial match of a fixed string). Each file or pattern should be
+separated by ':'.
