From mboxrd@z Thu Jan 1 00:00:00 1970 From: simon.guinot@sequanux.org (Simon Guinot) Date: Wed, 30 Sep 2015 11:10:45 +0200 Subject: [PATCH v4 4/5] ARM: mvebu: add DT support for Seagate Personal Cloud In-Reply-To: <1443604246-29844-1-git-send-email-simon.guinot@sequanux.org> References: <1443604246-29844-1-git-send-email-simon.guinot@sequanux.org> Message-ID: <1443604246-29844-5-git-send-email-simon.guinot@sequanux.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch adds DT support for the Seagate Personal Cloud 1 and 2-Bay. Here are some information allowing to identify these devices: Product name | Personal Cloud | Personal Cloud 2-Bay Code name (board/PCB) | Cumulus | Cumulus Max Model name (case sticker) | SRN21C | SRN22C Material desc (product spec) | STCRxxxxxxx | STCSxxxxxxx Chipset list: - SoC Marvell Armada 370 88F6707, CPU @1GHz - SDRAM memory: 512MB DDR3 667MHz (16-bits bandwidth) - SPI flash 1MB (Macronix MX25L8006E) - 1 or 2 SATA internal ports - 1 Ethernet Gigabit port (PHY Marvell 88E1518) - 1 USB3 host port (PCIe controller ASM1042) - 1 USB2 host port (SoC) - 2 push buttons (power and reset) - 1 SATA LED (bi-color, white and red) Note that support for the white SATA LED is missing. A dedicated LED driver is needed.

Changes for v3: - Fix spelling for Personal Cloud DTS files: 'personal' instead of 'personnal'. - Add Andrew's Acked-by. Changes for v4: - Add "broken-idle" property in the coherency-fabric DT node. diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index a0cc0b63db41..8e83da127a9c 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -712,6 +712,8 @@ dtb-$(CONFIG_MACH_ARMADA_370) += \ armada-370-rd.dtb \ armada-370-seagate-nas-2bay.dtb \ armada-370-seagate-nas-4bay.dtb \ + armada-370-seagate-personal-cloud.dtb \ + armada-370-seagate-personal-cloud-2bay.dtb \ armada-370-synology-ds213j.dtb dtb-$(CONFIG_MACH_ARMADA_375) += \ armada-375-db.dtb diff --git a/arch/arm/boot/dts/armada-370-seagate-personal-cloud-2bay.dts b/arch/arm/boot/dts/armada-370-seagate-personal-cloud-2bay.dts new file mode 100644 index 000000000000..3c91f9821c89 --- /dev/null +++ b/arch/arm/boot/dts/armada-370-seagate-personal-cloud-2bay.dts @@ -0,0 +1,51 @@ +/* + * Device Tree file for Seagate Personal Cloud NAS 2-Bay (Armada 370 SoC). + * + * Copyright (C) 2015 Seagate + * + * Author: Simon Guinot + * + * This file is licensed under the terms of the GNU General Public + * License version 2.
