From 654cd22227e6394f17b2f7c10d9fa9130db193fe Mon Sep 17 00:00:00 2001 From: Josua Mayer Date: Tue, 17 May 2022 11:54:31 +0300 Subject: [PATCH] ARM: dts: imx6qdl-sr-som: update phy configuration for som revision 1.9 Since SoM revision 1.9 the PHY has been replaced with an ADIN1300, add an entry for it next to the original. As Russell King pointed out, additional phy nodes cause warnings like: mdio_bus 2188000.ethernet-1: MDIO device at address 1 is missing To avoid this the new node has its status set to disabled. U-Boot will be modified to enable the appropriate phy node after probing. The existing ar8035 nodes have to stay enabled by default to avoid breaking existing systems when they update Linux only.
