4 Subject: [PATCH] net: phy: add driver for MediaTek SoC built-in GE PHYs
5
6 Some of MediaTek's Filogic SoCs come with built-in gigabit Ethernet
7 PHYs which require calibration data from the SoC's efuse.
8 Despite the similar design the driver doesn't share any code with the
9 existing mediatek-ge.c.
10 Add support for such PHYs by introducing a new driver with basic
11 support for MediaTek SoCs MT7981 and MT7988 built-in 1GE PHYs.
