The effort has moved in-house at NXP and I'll be carrying it forward, continuing from this v2 rather than restarting from zero. Vincent, thanks for the v1->v2 groundwork. I'll keep your authorship on the patches that originate from your series (Co-developed-by plus your Signed-off-by) and build on top; I'll send you v3 off-list first, as you offered. A v3 is in preparation and will come as an RFC, with the v2 review comments addressed. Vincent, if you're OK with the handoff, a short ack here would help make the transition visible to the reviewers. Thanks. /Jan
