oh, excellent catch - thank you!

nice, thank you!

do the ARM maintainers still want separate pull-requests for 32-bit
and 64-bit .dts/defconfig/etc. changes?
you might want to move the three latest commits from v4.13/dt64 to
v4.13/dt32 in that case, but this should be trivial (since these
patches don't depend on anything else)

you're welcome, hopefully more to follow!
