+Each node's ``compatible`` property is tried in order. The
+:ref:`bindings <dt-binding-compat>` are uniquely identified by a pair of

+:ref:`on-bus <dt-bindings-on-bus>`), where the
+:ref:`on-bus <dt-bindings-on-bus>` may be unspecified. A specified

+
+``manufacturer,device-i2c.yaml``
+

+
+   compatible: "manufacturer,device"

+
+If more than one matching binding for a compatible is found, an error is raised.
 
 The ``manufacturer`` prefix identifies the device vendor. See
