Thank you for reaching out to them! Do we actually support spear1380 with the mainline kernel? I've never seen anything other than 1310 and 1340 models mentioned. If Schneider have additional patches on top of mainline for this, it would be good to get those merged as well. Is there a kernel source tree available somewhere? Rob Herring had mentioned that it would be nice to see SPEAr get removed eventually because it was only partially converted to devicetree, with some AUXDATA() (on 300/310/320/6xx) and some dmaengine channel data still in source format. These need to be finished before we can kill off AUXDATA. Arnd
