From 351729ca445d4822502ff7117f8213832e753f91 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Beh=C3=BAn?= Date: Tue, 15 Mar 2022 16:37:27 +0100 Subject: arm: mvebu: dts: turris_mox: fix non-working network / MDIO MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 0934dddc6436 ("arm: a37xx: Update DTS files to version from upstream Linux kernel") ported Linux's device-tree files for Armada 3720 SOCs. This broke network on Turris MOX, because the SOC's MDIO bus in U-Boot currently isn't probed via DM as it's own device, but is registered as part of mvneta's driver, which means that pinctrl definitions are not parsed for the MDIO bus node. Also mvneta driver does not consider "phy-handle" property, only "phy". For now, fix this by adding armada-3720-turris-mox-u-boot.dtsi file returning the MDIO to how it was defined previously. A better solution (using proper mvmdio DM driver) is being work on, but will need testing on various boards, and we need the bug fixed now for the upcoming release.
