From 2a7232371ab27e13f9d131a25111e951c3c729dd Mon Sep 17 00:00:00 2001 From: Eugeniy Paltsev Date: Mon, 7 Oct 2019 19:10:50 +0300 Subject: [PATCH] NET: DW: fix regression for ARC boards The commit 642b80d256e ("net: designware: drop compatible altr, socfpga-stmmac") breaks designware ethernet for all ARC boards. It removes "altr, socfpga-stmmac" compatible from "drivers/net/designware.c" without changing compatible in the boards which use it. Fix that by adding "snps,arc-dwmac-3.70a" compatible string to "drivers/net/designware.c" and using it in ARC boards device tree.
