Ethernet on my CycloneV broke since 4.9.124
Hi, The patch "net: stmmac: socfpga: add additional ocp reset line for Stratix10" introduce in 4.9.124 broke the ethernet on my CycloneV board. When I boot i have this issue : socfpga-dwmac ff702000.ethernet: error getting reset control of ocp -2 socfpga-dwmac: probe of ff702000.ethernet failed with error -2 Reverting the commit : 6f37f7b62baa6a71d7f3f298acb64de51275e724 fix the issue. Thanks, Clement
