From e6015c1f8a9032c2aecb78d23edf49582563bd47 Mon Sep 17 00:00:00 2001 From: Seungwon Jeon Date: Fri, 9 May 2014 07:02:33 +0900 Subject: ARM: dts: disable MDMA1 node for exynos5420 This change places MDMA1 in disabled node for Exynos5420. If MDMA1 region is configured with secure mode, it makes the boot failure with the following on smdk5420 board. ("Unhandled fault: imprecise external abort (0x1406) at 0x00000000") Thus, arndale-octa board don't need to do the same thing anymore.
