+Subject: [PATCH] phy: marvell: phy-mvebu-a3700-comphy: Rename HS-SGMMI to
+ 2500Base-X
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Comphy phy mode 0x3 is incorrectly named. It is not SGMII but rather
+2500Base-X mode which runs at 3.125 Gbps speed.
+
+Rename macro names and comments to 2500Base-X.
