From 3d6a1a7874c991c4bd9719bf0a92ab6630034c67 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Sun, 12 Jan 2025 17:57:33 +0100 Subject: [PATCH] realtek: switch RTL8231 driver for D-Link DGS-1210 Update the common external GPIO DTSI file for the DGS-1210 devices to use an MDIO device on the auxilairy MDIO bus, as the original driver was doing behind the screen. Switching to the new driver will allow for full pin-control and will no longer reset pin config set by the bootloader.
