From 82f8582feef4c048ee7ef0155a71c23614a7856d Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Sat, 5 Dec 2015 21:16:44 +0800 Subject: [PATCH] ARM: dts: sun4i: Add DRAM gates The DRAM gates controls direct memory access for some peripherals. These peripherals include the display pipeline, so add the required gates to the simplefb nodes as well.
