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.
