From d83010f87ab31861eacac1ffe1278f655a376268 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Fri, 30 Nov 2018 15:26:16 +0000 Subject: [PATCH] ARM: dts: r8a7744: Initial SoC device tree Basic support for the RZ/G1N (R8A7744) SoC. Added placeholders to avoid compilation error with the common platform code.
