Two comments;
1) Use '-M' when posting patches that rename files, it makes for a much
   smaller diff.  :-)
2) Now that I see this patch, it's rather striking that .dtsp and .dtsip
   are horible extensions (so are .dts and .dtsi for that matter, but
   this just kicks it up a notch). Can we not do something better?

Can we do something else here; First, does the old style /include/
directives cause any problems existing .dts files? I know it won't work
if a /include/'ed file uses a #include statement, but the other way
around should be fine. Can we instead move the entire tree over to
building with the CPP enabled? Overall it will be less horribleness for
the end user.
