    Vincent Donnefort authored
    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.
