I always used a bamboo.dts -> dtb out of my kernel tree and used that one along time, so I never saw this issue.
I tried to convert this bamboo.dts file in qemu into a dtb file today and saw that it does not compile (nether with nor without that new patch, the patch only pointed me to that file).

paelzer@HeliosPrime ~/Desktop/KVM/ppc_port/kvm-userspace-vio/qemu/pc-bios $ dtc -I dts -O dtb -o bamboo.dtb2 bamboo.dts
DTC: dts->dtb  on file "bamboo.dts"
bamboo.dts:20 syntax error
FATAL ERROR: Couldn't read input tree

Is this correct/expected atm or do we have to fix something here before this goes upstream ?
