I still fundamentally disagree with the necessity of "validating" my 
ability to understand my own trivial 3-property binding that I wrote, 
but whatever... v2 can have this which I've made up out of thin air 
since I have no real-world reference to hand:

examples:
   - |
     pmu at 12340000 {
         compatible = "arm,bus-monitor-unit";
         reg = <0x12340000 0x40000>;
         label = "ddr_ch_1_2";
     };

Thanks,
Robin.
