From 1a48290edf6f78962b1d96008aea954b7b3e5969 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Tue, 12 Sep 2017 23:37:26 +0300 Subject: [PATCH] arm64: dts: renesas: initial Eagle board device tree Add the initial device tree for the R8A77970 SoC based Eagle board. The board has 1 debug serial port (SCIF0); include support for it, so that the serial console can work. Based on the original (and large) patch by Vladimir Barinov .
