So, *how* do you think things are sorted here? Alphabetical by label? Or
by node name? Or by unit address? I guess I'm seeing you meant unit
address. But pcie@f8000000 is also out of order then. I guess maybe
that's the only one then.

Ah, sorry. I'll try to go with the rockchip,dwc3.txt names better.
There are a few extra clocks here now, but I think those might only be
for USB3 support, which isn't really working yet. I'll either document
them or drop them.

Similar story; this is only used for some of the hacky stuff Rockchip is
doing for USB3/TypeC stuff out of tree. I'll either document it or drop
it (as I'm not actually using it yet).
