From ef3f08c83fd186ab4bbad6a6250c5a347fbf6551 Mon Sep 17 00:00:00 2001 From: Kazuya Mizuguchi Date: Wed, 1 Feb 2017 09:42:04 +0100 Subject: [PATCH] arm64: dts: r8a7796: salvator-x: Fix EthernetAVB PHY timing Set PHY rxc-skew-ps to 1500 and all other values to their default values. This is intended to to address failures in the case of 1Gbps communication using the by salvator-x board with the KSZ9031RNX phy. This has been reported to occur with both the r8a7795 (H3) and r8a7796 (M3-W) SoCs.
