From b64d814257b027e29a474bcd660f6372490138c7 Mon Sep 17 00:00:00 2001 From: Pali Rohár Date: Mon, 7 Sep 2020 13:27:17 +0200 Subject: arm64: dts: marvell: espressobin: Add ethernet switch aliases MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Espressobin boards have 3 ethernet ports and some of them got assigned more then one MAC address. MAC addresses are stored in U-Boot environment. Since commit a2c7023f7075c ("net: dsa: read mac address from DT for slave device") kernel can use MAC addresses from DT for particular DSA port. Currently Espressobin DTS file contains alias just for ethernet0. This patch defines additional ethernet aliases in Espressobin DTS files, so bootloader can fill correct MAC address for DSA switch ports if more MAC addresses were specified. DT alias ethernet1 is used for wan port, DT aliases ethernet2 and ethernet3 are used for lan ports for both Espressobin revisions (V5 and V7).
