Hi Arnd, I am quite busy this days but as soon I get some free time I will take care of the DT conversion for the Lacie boards. Basically, we need to fix some minor issues with the Thomas patches: ARM: kirkwood: convert d2net_v2 to DT ARM: kirkwood: convert LaCie Net{2, 5}Big v2 platforms to DT And also a DT binding must be added to the LED driver leds-netxbig.
