Subject: [PATCH] dt-bindings: watchdog: restrict node name suffixes
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Make the pattern matching node names a bit stricter to improve DTS
consistency.  The pattern is restricted to -N suffixes to decimal
numbers.
