From 3bac348387b6aab8a906c752980b853fb9d85df8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sun, 23 Jul 2023 22:41:18 +0200 Subject: [PATCH] bcm53xx: add BCM53573 Ethernet fix sent upstream for v6.6 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It seems that DSA-based b53 driver never worked with BCM53573 SoCs and BCM53125. In case of swconfig-based b53 this fixes a regression. Switching bgmac from using mdiobus_register() to of_mdiobus_register() resulted in MDIO device (BCM53125) having of_node set (see of_mdiobus_register_phy()). That made downstream b53 driver read invalid data from DT and broke Ethernet support.
