| Subject: [PATCH 009/286] arm64: dts: r8a7795: 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. |
