+Subject: [PATCH 15/15] net: dsa: mt7530: explain exposing MDIO bus of MT7531AE
+ better
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Unlike MT7531BE, the GPIO 6-12 pins are not used for RGMII on MT7531AE.
+Therefore, the GPIO 11-12 pins are set to function as MDC and MDIO to
+expose the MDIO bus of the switch. Replace the comment with a better
+explanation.
