From 45b03799ad3ca6f626d49c0e5fccc694431f6c25 Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Mon, 25 Nov 2019 12:43:51 +0100 Subject: net: dsa: sja1105: fix sja1105_parse_rgmii_delays() [ Upstream commit 9bca3a0a923fc3f0fb9e41391be1d0f291e86858 ] This function was using configuration of port 0 in devicetree for all ports. In case CPU port was not 0, the delay settings was ignored. This resulted not working communication between CPU and the switch.
