Right. I didn't realize by bootloader was passing the DTB from an old kernel. So after fixing my boot I got the patches working N800 and N810: I was able to read and write on old JFFS2 file systems without any issues. So you can add for the series: Tested-by: Aaro Koskinen <aaro.koskinen@xxxxxx> > In earlier version of this patchset there was fixup present, so driver > worked even without compatible.

N8x0 support is also "under development", and we are fine with updating and always using latest in-tree DTs.
