Platform drivers are still usable with DT systems. We used that fact
when converting platform based machines over to DT, one driver at a
time. Look in the git history for kirkwood devices. e.g. somewhere
around v3.7, arch/arm/mach-kirkwood. board-dt.c, and the various
board-*.c files, and the DT files in the usual place.

It is not just the move to DT where things are different. Kernel APIs
are not stable. So your old drivers might not even compile with a
current kernel.
