Hi Arnd,

thanks for the ack!

Unfortunately, I has not (yet) been tested on cm-a510 nor dove-db but
from the status of the exisiting non-DT setup files I strongly doubt that
anyone is using current mainline kernel for mach-dove.

I suggest to keep non-DT support until we have pinctrl and gpiolib drivers
done. Thomas Petazzoni and I have been working on pinctrl that will be
posted in a few days and gpiolib driver needs some more cleanup but is
basically working. Until then I guess most of the other orion drivers have
DT support (eth and xor IIRC).

After that I am definitely fine with removing non-DT support although
there is neither DT support in u-boot installed on my CuBox nor
mach-dove support in mainline u-boot.

Sebastian
