This patch adds DT support for the Seagate NAS 2 and 4-Bay. Here are some information 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. Signed-off-by: Vincent Donnefort <vdonnefort@gmail.com> Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
