It is not a new property. Name was being used for description as 
description was not present in device tree. A skiboot patch adding 
description to device tree have been posted. This patch reads those 
description instead of copying name itself into description. And we fall 
back to reading name into description to not break the comaptibility 
with older firmware.

Thanks
