Hi Andrew
There has been a move to license all the 370 and XP DTS files under
dual GPL and X11. Are you willing to add X11?
No problem, will fix.

It would be nice to have
stdout-path = &uart0;
here. That will help with boot loaders, using this DT file, and it a
step towards removing the console=ttyS0,115200.

Are both serial ports usable?
Could you document the pinout for the console?
Thanks
Andrew
The serial console pinout is :
[RXD|(gap)|3.3v|GND|TXD]
I've been documenting the hardware extensively in my blog here:
http://ncrmnt.org/wp/2015/02/15/debian-dlink-dns-327l-the-guide/
Pictures of the PCB are all there.
The second UART is used to interface with weltrend mcu only.
I'll resubmit the patches with fixes sometime tomorrow evening (GMT+4).
Hopefully I'll also find out is hardware freezes with cpuidle enabled
are
still there on 4.0-rc7.
