Hi Christoph

I just tried compiling this with 3.19-rc1:

  DTC     arch/arm/boot/dts/kirkwood-pogo_e02.dtb
ERROR (duplicate_label): Duplicate label 'pinctrl' on /ocp at f1000000/pinctrl at 10000 and /ocp at f1000000/pin-controller at 10000
ERROR: Input tree has errors, aborting (use -f to force output)

It is normal to say here, after the --- what you have changed since
the previous version.

This failed to apply. cnm was added Wed May 14 2014, so i guess you are not using 3.19-rc1?

This is not what i was expecting. I would expect it to be

                stdout-path = &uart0;
