Hi Michael & Stephen,

Only the first patch (a tree-wide patch to rename include files)
of my v2 was merged, so I thought I'd send the second patch again. Since
checkpatch complained that DT includes must be in their own patch,
I just did that and decided to send a V3 instead of a RESEND.

Changes from v2:
- Previous patch [1/2] was merged
- Split previous patch [2/2] into two patches

Cheers,
-Paul
