Subject: [PATCH V3 4/4] ARM: dts: BCM5301X: Enable extra CPU ports for Netgear R8000
Date: Wed, 12 Aug 2026 15:27:55 +0200 [thread overview]
Message-ID: <20260812132755.32585-4-zajec5@gmail.com> (raw)
In-Reply-To: <20260812132755.32585-1-zajec5@gmail.com>
From: Rafał Miłecki <rafal@milecki.pl>
Just because port 8 is a preferred CPU port (because it provides a full
switch functionality) it doesn't mean other ones can't be used. Let
software decide which CPU port to use.
Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

After some extra research I discovered we can't blindly update all
BCM5301X (Northstar) devices enabling all 3 ports (5, 7 and 8).
Sometimes extra ports require fixed link but it seems to be device
specific.
