I think I just ran into a snag which indicates what your are saying.

Marc's set of patches above are implemented using struct of_device which
appears to have been removed from mainline powerpc and replaced entirely
with platform_device.  That is probably what he meant when he talked
about bit-rot.

How do I go about doing the "new device-tree" integration?  I am not
familiar with that at all.

Thanks,
Robin
