On the other hand, some DTs for iPhones mention "apple", not APPL: https://www.theiphonewiki.com/wiki/D211AP/Device_Tree https://www.theiphonewiki.com/wiki/D331AP/Device_Tree https://gist.github.com/bazad/1faef1a6fe396b820a43170b43e38be1 Although I am not sure how reliable are the sources.
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,".
