Looks like specific to 2.6.14-DENX (kernel.org shows the additional "parent" 
parameter only starting with 2.6.15).
http://www.denx.de/cgi-bin/gitweb.cgi?p=linux-2.6-denx.git;a=blobdiff;h=a9e72ac3fb9fd066ebc5607bd28cfdd4ba8f010e;hp=95d607a48f06edd22c6be64e0feaf74d1aa63467;hb=3692e2d8099f19a4d1ff95df94cc82b394f86931;f=include/linux/device.h

We likely need to find a way to specifically identify this tree.
