[PATCHv2] ARM: dts: BCM5301X: AC87U: specify switch
From: Rosen Penev <hidden>
Date: 2026-09-07 19:59:40
Also in:
linux-devicetree, lkml
Subsystem:
broadcom bcm5301x arm architecture, the rest · Maintainers:
Florian Fainelli, Hauke Mehrtens, Rafał Miłecki, Linus Torvalds
Add labels to clarify which port is what.
Also set WAN MAC from nvram, which is offset by 1. Set in dts to avoid
having to handle this in userspace.
Signed-off-by: Rosen Penev <redacted>
