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) Signed-off-by: Arnaud Ebalard --- arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/armada-370-synology-ds213j.dts | 351 +++++++++++++++++++++++ 2 files changed, 353 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/armada-370-synology-ds213j.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 38c89cafa1ab..95387b59ebb2 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -495,7 +495,8 @@ dtb-$(CONFIG_MACH_ARMADA_370) += \ armada-370-mirabox.dtb \ armada-370-netgear-rn102.dtb \ armada-370-netgear-rn104.dtb \ - armada-370-rd.dtb + armada-370-rd.dtb \ + armada-370-synology-ds213j.dtb dtb-$(CONFIG_MACH_ARMADA_375) += \ armada-375-db.dtb dtb-$(CONFIG_MACH_ARMADA_38X) += \ 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..3cba5c7d36f1 --- /dev/null +++ b/arch/arm/boot/dts/armada-370-synology-ds213j.dts @@ -0,0 +1,351 @@ +/* + * 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.
