From 60ed9eb9605656c19ca402b7bd3f47552e901601 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Mon, 13 Feb 2023 02:33:14 +0000 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.
