Yes.

 New DTSI files (see SC8280XP,

Perhaps it slipped through review.. Partially my bad.


Such reshuffle can cause conflicts thus

Almost any addition or removal also causes conflicts, because git is
not as smart as we would like it to be. If the commit is structured
properly (i.e. it *only* changes the order and nothing else),
decompiling the dtbs before and after applying it and using a tool
like meld that can find similar chunks of text at different offsets
review is definitely possible, though not very pleasant (you can't
just diff them, as order is preserved & phandles change due to that)
as you have to look at it manually and can't tell much by just taking
a look at the email.
