Subject: [PATCH v2 1/3] ARM: mvebu: add DT support for Seagate NAS 2 and 4-Bay
Date: Fri, 11 Sep 2015 23:52:51 +0200 [thread overview]
Message-ID: <1442008373-19184-2-git-send-email-simon.guinot@sequanux.org> (raw)
In-Reply-To: <1442008373-19184-1-git-send-email-simon.guinot@sequanux.org>
From: Vincent Donnefort <vdonnefort@gmail.com>
This patch adds DT support for the Seagate NAS 2 and 4-Bay.
Here are some informations allowing to identify these devices:
Product name | Seagate NAS 2-Bay | Seagate NAS 4-Bay
Code name (board/PCB) | Dart 2-Bay | Dart 4-Bay
Model name (case sticker) | SRPD20 | SRPD40
Material desc (product spec) | STCTxxxxxxx | STCUxxxxxxx
Chipset list (common):
- SoC Marvell Armada 370 88F6707, CPU @1.2GHz
- SDRAM memory: 512MB DDR3 600MHz (16-bits bandwidth)
- NAND flash 256MB, 8-bits (Micron MT29F2G08AAB or Hinyx H27U2G8F2CTR-BC)
- 2 SATA II ports (SoC)
- 1 Ethernet Gigabit ports (PHY Marvell 88E1518)
- 2 USB3 host ports (PCIe controller ASM1042)
- GPIO fan (4 speeds)
- External I2C RTC (MCP7940NT)
- 3 push buttons (power, backup and reset)
- 2 SATA LEDs (bi-color, blue and red)
- 1 power LED (bi-color, blue and red)
Only on 4-Bay models:
- 2 extra SATA III ports (PCIe AHCI controller Marvell 88SE9170)
- 1 extra Ethernet Gigabit ports (PHY Marvell 88E1518)
- I2C GPIO expander (PCA9554A)
- 2 extra SATA LEDs (bi-color, blue and red)
Note that support for the white SATA LEDs associated with HDDs 0 and 1
is missing. A dedicated LED driver is needed.

Changes for v2:
- Rename DTS files using the products names.
- Update model and compatible properties as well.
- Add some informations allowing to identify the devices in the commit
message and in the DTS files headers.
- Remove duplicated rtc alias in armada-370-seagate-nas-xbay.dtsi.
