From b04650d40f4b970e67cd78295ec2a3d00d959866 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 20 Apr 2017 11:50:47 +0200 Subject: arm64: dts: r8a7796: salvator-x: Set drive-strength for ravb pins The EthernetAVB should not depend on the bootloader to setup correct drive-strength values. Values for drive-strength where found by examining the registers after the bootloader has configured the registers and successfully used the EthernetAVB. Based on commit 7d73a4da2681dc5d ("arm64: dts: r8a7795: salvator-x: Set drive-strength for ravb pins").
