+From a6f143af419bfc3f52d82e88ac033d9833e720af Mon Sep 17 00:00:00 2001

+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.
+Add support for these PHYs to the mediatek-ge driver if built for
+MediaTek's ARM64 SoCs.
