From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Horman Date: Sat, 17 Jan 2015 00:58:42 +0000 Subject: [PATCH 09/11] ARM: shmobile: r8a7740 dtsi: Add memory-controller node Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org From: Geert Uytterhoeven 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.
