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 v2:
- Rename DTS files using the products names.
- Update model and compatible properties as well.
- Add some information allowing to identify the devices in the commit
message and in the DTS files headers.
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.
