Mon Dec 23 10:42:26 EST 2013
This patch adds DT board setup for the LaCie NAS LaPlug.
Chipset list:
- CPU MARVELL 88FR131 800Mhz
- SDRAM memory: 128MB DDR2-800 400Mhz
- 1 Ethernet Gigabit port (PHY MARVELL 88E1318)
- 1 Mini PCI-Express port
- 1 NAND 512 MB
- 1 push button
- 2 LEDs (red and blue)
- 4 USB Ports

Changes v1 -> v2:
- Rename the board from ns-plug to laplug, changes everywhere
accordingly
- Retab the files
- Use defines for GPIO active state and key input's name.
- Remove #*-cells in gpio-keys as this is not a bus
- Use kirkwood-6192.dtsi
