Add support for the Armada-370-based Seagate NAS

Hi,

This patch series adds support for the Seagate machines based on the Armada-370 Marvell SoC. This includes the Personal Cloud 1 and 2-Bay and the Seagate NAS 2 and 4-Bay.

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.

Thanks,

Simon

2.1.4

From: Vincent Donnefort <[email protected]>

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.

Hi Simon

Thanks for adding this information.

This patch adds DT support for the Seagate Personal Cloud 1 and 2-Bay.

Here are some informations 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.

2.1.4

This patch enables the following options needed by the Seagate Personal Cloud 1 and 2-Bay and the Seagate NAS 2 and 4-Bay:

SATA_AHCI
POWER_RESET_GPIO
RTC_DRV_DS1307
RTC_DRV_PCF8563

Additionnally this patch also enables NEW_LEDS which was missing for some reasons.
