Hi Drew,

For the StarFive device tree files we've agreed on sorting by / node, clock
references, and then other node references alphabetically. I'm not
insisting you should do the same, but it would be nice with some system to make
it clear where new node refences should go. Or maybe I'm just not seeing the
system you're already following.
