The DT and I2C namespaces are intended to be completely unrelated to
each other, both are needed in different systems.

Please stop going on about this, as has previously been discussed we do
*NOT* require board files, device tree files or any other kind of board
description to be included in mainline.  There is no expectation that we
will see anything instantiating any particular device included in the
kernel source, and in some cases such as ACPI this never happens at all.

I'm not sure how this can be made any clearer.
