From 8685c98d45c54346caf005de69988e13c731c533 Mon Sep 17 00:00:00 2001 From: Luiz Angelo Daros de Luca Date: Fri, 9 Feb 2024 02:03:43 -0300 Subject: net: dsa: realtek: get internal MDIO node by name The binding docs requires for SMI-connected devices that the switch must have a child node named "mdio" and with a compatible string of "realtek,smi-mdio". Meanwile, for MDIO-connected switches, the binding docs only requires a child node named "mdio". This patch changes the driver to use the common denominator for both interfaces, looking for the MDIO node by name, ignoring the compatible string.
