From 0e76f78cb3924050e969439eff6d5cc7685deb2b Mon Sep 17 00:00:00 2001 From: Arnaud Ebalard Date: Sat, 22 Nov 2014 00:46:49 +0100 Subject: arm: mvebu: add .dts file for Synology DS213j Synology DS213j is a 2-bay NAS powered by a Marvell Armada 370 (88F6710 @1.2Ghz). It is very similar on many aspects to previous 2-bay synology models based on Marvell kirkwood SoC. Here is a short summary of the device: - 512MB RAM - boot on SPI flash (64Mbit Micron N25Q064) - 1 GbE interface (Armada MAC connected to a Marvell 88E1512 PHY via SGMII) - 2 rear USB 2.0 ports (directly handled by the Armada 370) - 2 internal SATA ports handled by the Armada 370: 2 GPIO for presence, 2 for powering them - two front amber LED (disk1, disk2) controlled by the SoC - Seiko S-35390A I2C RTC chip - UART0 providing serial console - UART1 used for poweroff (connected to a TI MSP430F2111) - Fan handled via 4 GPIO (3 for speed, 1 for alarm) Acked-by: Andrew Lunn Signed-off-by: Arnaud Ebalard Link: https://lkml.kernel.org/r/20f1a03897df1d825b62abdd525e588a8e39b3ec.1416613429.git.arno@natisbad.org Signed-off-by: Jason Cooper --- arch/arm/boot/dts/armada-370-synology-ds213j.dts | 316 +++++++++++++++++++++++ 1 file changed, 316 insertions(+) create mode 100644 arch/arm/boot/dts/armada-370-synology-ds213j.dts (limited to 'arch/arm/boot/dts/armada-370-synology-ds213j.dts') diff --git a/arch/arm/boot/dts/armada-370-synology-ds213j.dts b/arch/arm/boot/dts/armada-370-synology-ds213j.dts new file mode 100644 index 000000000000..70fecde76ccb --- /dev/null +++ b/arch/arm/boot/dts/armada-370-synology-ds213j.dts @@ -0,0 +1,316 @@ +/* + * Device Tree file for Synology DS213j + * + * Copyright (C) 2014, Arnaud EBALARD + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version + * 2 of the License, or (at your option) any later version. + * + * Note: this Device Tree assumes that the bootloader has remapped the + * internal registers to 0xf1000000 (instead of the old 0xd0000000). + * The 0xf1000000 is the default used by the recent, DT-capable, U-Boot + * bootloaders provided by Marvell.
