From 877d4e3cedd18cd5a4cef7685b64af72f8322ac1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 9 Jul 2022 01:55:30 +0200 Subject: [PATCH] ixp4xx_eth: Set MAC address from device tree If there is a MAC address specified in the device tree, then use it. This is already perfectly legal to specify in accordance with the generic ethernet-controller.yaml schema. Signed-off-by: Linus Walleij Signed-off-by: David S.
