ARM: mvebu: add DT support for Seagate Personal Cloud
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. Signed-off-by: Simon Guinot <simon.guinot@sequanux.org> Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
