But looking at the Qualcomm tree I think I got 8916 wrong, it seems that
it should be "q6v56" and your patches indicates that the 8996 has a
q6v55 - which doesn't make sense to me and in some places there's
comments indicating it's version 6.

I asked you about this but I can't find an answer in any of your
replies.
