Hi Krzysztof, thanks for the feedback, I reached out to the developers who initiated the DT support for the new sam9x7 devices, he explained to me the general workflow, turns out the dts files aren't yet in linux-next. > I think you work on some really old Linux kernel, judging by CC list. Indeed, I used get_maintainer on an old kernel, my bad. Will update the CC list & the patch once the new DT files make it into linux-next.
