I've been away from this for a while so I might not be aware of the
current status.  Although portions of DPM have been discussed (namely
the infamous Operating Points brouhaha), it is unlikely that other
portions of DPM would be accepted in their current form.

Grab the patches for OMAP etc. and see what is needed.  So far as I
know there's no porting documentation.

Some arch-specific low power mode code is implemented in the main
kernel for platforms like OMAP, XScale PXA, etc.  Check the code for
the pm ops for those platforms.
