Hi Robert,
I tried just compiling the DVK530-LCD4 dtbo in theirs kernel directory,
then loading it on a plain debian image
(bone-debian-7.9-lxde-4gb-armhf-2015-11-12-4gb.img). It works, but here's
what I've got in the log:

I don't quite like those warnings/errors. Are they harmful ? Do you have a
hint how I could fix them ?
