I don't disagree (and at ELC I was trying to see who, if anyone, had
been reaching out to the FreeBSD folks since their DT files were very
far from what Linux uses afaict for am33xx), but I'm also not seeing
anything from non-Linux kernel folks on the devicetrees ML, or at least
my quick search failed.
