From 473baeab929444295b0530f8766e4becb6a08973 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Fri, 13 Oct 2023 12:33:13 +0200 Subject: [PATCH] ARM: dts: BCM5301X: Explicitly disable unused switch CPU ports MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When redescribing ports I assumed that missing "label" (like "cpu") means switch port isn't used. That was incorrect and I realized my change made Linux always use the first (5) CPU port (there are 3 of them). While above should technically be possible it often isn't correct: 1. Non-default switch ports are often connected to Ethernet interfaces not fully covered by vendor setup (they may miss MACs) 2. On some devices non-default ports require specifying fixed link This fixes network connectivity for some devices. It was reported & tested for Netgear R8000. It also affects Linksys EA9200 with its downstream DTS.
