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