This series was applied sooner than I had expected.
Simon and I were still discussing this series.

So I am afraid Simon is really not happy about it
because he was opposed to moving *.dts files
from vendor directories to arch directories.

Tom also mentioned as follows:

I'd like to know Tom's option about the device tree structure.
Let me confirm if my patch is doing right thing.
