one is currently used.

+Subject: [PATCH 1/3] dt-bindings: mtd: move partition binding to its own file
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Single partition binding is quite common and may be:
+1. Used by multiple parsers
+2. Extended for more specific cases
+
+Move it to separated file to avoid code duplication.
