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

+Subject: [PATCH] net: phy: mediatek-ge-soc: initialize MT7988 PHY LEDs default
+ state
+
+Initialize LEDs and set sane default values.
+Read boottrap register and apply LED polarities accordingly to get
+uniform behavior from all LEDs on MT7988.
+Requires syscon phandle 'mediatek,pio' present in parenting MDIO bus
+which should point to the syscon holding the boottrap register.
