[PATCH v3 1/1] ARM: mvebu: dts: Add dts file for DLink DNS-327L

From: Andrew Andrianov
Date: Sun May 03 2015 - 10:28:27 EST

DNS-327L is a 2-bay NAS with the following specs:
- 512MiB RAM
- 128MiB NAND Flash
- 1 GbE interface (Marvell PHY)
- 1 rear USB 3.0 port (via PCIe USB 3.0 controller)
- 2 internal SATA ports handled by the Armada 370:
uses 2 gpios for power control
- two front 2-color leds (amber + white) for both discs,
controlled by the SoC
- One white LED handled by SoC (USB)
- 3 buttons. Power handled by weltrend, USB and
RESET (on the bottom) are wired via GPIOs
- Unidentified i2c device at address 0x13 (via i2cdetect)
- UART0 providing serial console
- Weltrend MCU serving for RTC, temperature, fan control,
and power button handling interfaced via UART1
(Handled via userspace dns320l-daemon)
