   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, so add support for these PHYs by introducing a
  10 new driver for only MediaTek's ARM64 SoCs.
