Isn't this something that we may want to change at some point? My
understanding is that GPIO hogs are permanent, so it won't be possible
to grab GPIO R.6 and change this.

Are there any plans to allow setting this at runtime?

This doesn't belong here. The ordering is by unit-address and everything
without unit-address needs to move after the nodes with unit-addresses
and be sorted alphabetically.

Ugh... looking at the bindings for this the naming here is rather
unfortunate. emc-tables@3 and emc-table@*... the top-level emc-tables
are really tables, but the emc-table@* are really entries or rows in
that table, not tables themselves. It's also rather unfortunate that we
duplicate the frequency in both the "reg" and "clock-frequency"
properties. One of them would've been enough.

Anyway, looks like this has basically been like this since forever, so
not much that can be done about it.

Again, the memory-controller node needs to be sorted differently. There
are other occurrences of this throughout the file.
