From f4c6d004eac803cf90452c94ec5f3210c2d44c01 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 14 Jan 2015 12:13:01 +0100 Subject: [PATCH] ARM: shmobile: r8a7740 dtsi: Add memory-controller node Add a device node for the DDR3 Bus State Controller (DBSC3). The DBSC3 is located in the A4S PM domain, which must not be powered down, else the system will crash. This has no visible effect for now, as A4S was never turned off anyway because its child PM domain A3SM contains the CPU core.
