+Subject: [PATCH] net: ethernet: sunxi: Add new compatibles
+
+The Allwinner A10 compatibles were following a slightly different compatible
+patterns than the rest of the SoCs for historical reasons. Add compatibles
+matching the other pattern to the ethernet driver for consistency, and keep the
+older one for backward compatibility.
