Hi Marc,
We had a quite fruitful discussion in this mail thread regarding this
topic and Ludovic acked it so recently I have asked Thomas if he still
needs this v3 patch with detailed explanation especially as v2 version
of stm32-gpio patch has been already taken by Linus. However if you
require I can resend v3 of this patch only with this detailed explanation.

That'd be useful. The changelog is the only thing that will be left from
this discussion, so it'd better be complete and accurate. If you quickly
send a v3 for this single patch, I'll queue it right away.

Any update on this? I'd like to queue this for 4.17, but Thomas'
comments should be addressed before that happens. Ca you please respin a
version with a better change log and the various review tags?
