From 5f45cec40402188a269dd56e9a1a569cc4849014 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Fri, 26 Aug 2016 23:21:42 +0300 Subject: ARM: dts: wheat: initial device tree Add the initial device tree for the R8A7792 SoC based Wheat board. The Wheat board itself has no serial ports wired up, the USB serial chips are situated on a separate debug board and one of them is connected to SCFI0 -- include unconditional support for it, so that the serial console can work. Based on the original (and large) patch by Vladimir Barinov .
