Thanks for the link, didn't searched the pinctrl driver dir..

Anyway I still think that we should (re-)sync the barebox gpio code with
linux. The sync can start with adding the of_xlate support like it is
done in linux? This was also my reason for completely revert your patch
since a gpiolib sync would adapt the of_xlate handling anyway.
