+description: |+
+  The device tree allows to describe the layout of CPUs in a system through
+  the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
+  defining properties for every cpu.
+
+  Bindings for CPU nodes follow the Devicetree Specification, available from:
+
+  https://www.devicetree.org/specifications/
+
+properties:
+  compatible:
+    items:
