For reference, these are the examples I see in the device tree dump for the mac mini: AAPL,unit-string = "00000000"; AAPL,slot-name = "Slot- 1"; device_type = "AAPL,display-crossbar"; device_type = "AAPL,atc-dpxbar"; device_type = "AAPL,atc-dpphy"; device_type = "AAPL,atc-dpin"; In addition, every node has a AAPL,phandle property (corresponding to linux,phandle), and some have a AAPL,unit-string. As in the iphones, only the cpu nodes do use "apple,".
