The split of files seems fine, but a little more information
about what this chip is used for would help, so that developers
looking at the git history later can have an idea.

I don't understand these, can you turn these into full
english sentences? What checkpatch errors do you see and
why should I ignore them? What is PESW-2604 and how does
it relate to PLZP1600?

I don't see any references to ti-dp83867.h here, maybe leave
the #include to a later patch that actually starts using it?

Is this an off-by-one error or do you intentionally
leave out the last bit of the 4GB address space?

If the last byte is actually addressable, please just
use #size-cells=<2> and make it the full 0x100000000.
