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,".
