From fff9316268e44d70cd618d32376a085ab8205e89 Mon Sep 17 00:00:00 2001 From: Pawel Dembicki Date: Tue, 5 Mar 2024 15:23:31 +0100 Subject: [PATCH] kirkwood: Add missing phy-mode and fixed links Copied from original Andrew's Lunn commit message: The DSA framework has got more picky about always having a phy-mode for the CPU port. The Kirkwood Ethernet is an RGMII port. Set the switch to impose the RGMII delays. Additionally, the cpu label has never actually been used in the binding, so remove it. This commit backport change from upstream and fix downstream EA3500 dts.
