From 1ff39f9e986dbe99b2b1232cf0307437b20b41d2 Mon Sep 17 00:00:00 2001 From: Markus Stockhausen Date: Fri, 20 Feb 2026 07:55:24 +0100 Subject: [PATCH] realtek: mdio: setup polling for RTL8261 Startup of mdio on a RTL8216 based device currently shows the following warnings. [1.948608] skip polling setup for unknown PHY 001ccaf3 on port 0 [1.968920] skip polling setup for unknown PHY 001ccaf3 on port 8 [1.989171] skip polling setup for unknown PHY 001ccaf3 on port 16 [2.009704] skip polling setup for unknown PHY 001ccaf3 on port 20 [2.030209] skip polling setup for unknown PHY 001ccaf3 on port 24 [2.052270] realtek-otto-serdes-mdio 1b000000.switchcore:mdio-serdes: Realtek SerDes mdio bus initialized, 12 SerDes, 64 pages Add the phy detection to the mdio bus so that polling setup works. While we are here sort the phy ids alphabetically.
