From 3737c6aaf22dc6f515a7d4cf88dfe6e514414f88 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ar=C4=B1n=C3=A7=20=C3=9CNAL?= Date: Tue, 20 Sep 2022 20:25:48 +0300 Subject: [PATCH] dt-bindings: net: dsa: mediatek,mt7530: change mt7530 switch address MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In the case of muxing phy0 of the MT7530 switch, the switch and the phy will have the same address on the mdio bus, 0. This causes the ethernet driver to fail since devices on the mdio bus cannot share an address. Any address can be used for the switch, therefore, change the switch address to 0x1f.
