Well, if the spidev driver isn't there you'll need to fix that... it might also be worth trying mainline here in case there are any fixes that stable didn't backport. From a quick scan nothing is jumping out though. As far as I can see that's the issue, the driver just didn't get loaded. > If i however put the spidev definition in the main DTS file everything works as expected: I've no idea what, if any, special considerations there are around overlays or the specific mechanism you're using to load them on your system, you should talk to the DT people about that I guess? I wouldn't have expected the use of an overlay to make any difference.
