Actually I don't have the NXP tree but a Digi tree, which is probably based on it. I think, generally, this is a bit of a grey area. While I would always keep a SoB if I base a patch on an old mailing list patch submission (and contact the person if possible first to ask) I'm not sure if a SoB from a "random git tree" indicates they wish a mainline submission with their name (some people may want credit and others not want to be considered responsible for bugs...). I didn't see a submission of this version (with the gpr information coming from the DT) on the mailing lists, only the initial version using the platform callback that was NAKd (I may have missed it though).
