From 7d73a4da2681dc5d04e8ed9f4aa96c1deed2dbc5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Niklas=20S=C3=B6derlund?= Date: Mon, 5 Dec 2016 18:43:10 +0100 Subject: [PATCH] arm64: dts: r8a7795: salvator-x: Set drive-strength for ravb pins MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
