From cf8f3a7a044d57f3a0c5e14e97b8926c212f31f0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ar=C4=B1n=C3=A7=20=C3=9CNAL?= Date: Fri, 10 Feb 2023 21:25:03 +0300 Subject: [PATCH] arm: dts: mt7623: 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.
