-Subject: [PATCH] net: phy: add MediaTek Gigabit Ethernet PHY driver
-
-Add support for MediaTek Gigabit Ethernet PHYs found in MT7530 and
-MT7531 switches.
-The initialization procedure is from the vendor driver, but due to lack
-of documentation, the function of some register values remains unknown.
