Greg, Kishon,
it might be best if one of you merged the whole set, except perhaps the
arm64 device tree change, because there's a lot of build-time
dependencies here that would be non-trivial to resolve otherwise. I
could prepare branches that model the dependencies correctly, but the
USB branch with the last two patches is ultimately going to depend on
all the rest anyway and pull that in, so the result is the same.
