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.

I'm not aware about plans to change that charging hog.

It's not a problem to remove the hog. I don't understand why you're
saying that it's permanent. We have such hogs in Nexus7 DT for the 3G
modem pins. If we'll ever have a driver for that modem, then we will
remove those hogs, not a problem.

Logically it belongs here, since mux uses i2c2. All other DTs do the same.

It's emc-tables@3 here because initially there were other tables that I
removed during preparation of the DT for upstream. Those tables were
untested and looked questionable to me.

Please feel free to reorder it.

Memory-controller node is placed on purpose in the end of DT to keep it
readable. Those huge timings make it unreadable. I don't want to change
it. Alternatively, we can factor out timings into separate DTSI, but
it's unnecessary to me. I leave it up to you to decide what to do.

I'll reorder couple nodes alphabetically, those that don't have address
and were missed by me. The by-address nodes are all okay to me.

Please feel free to reorder nodes to yours liking by yourself while
applying if I'll miss something.
