   4Requires node properties:
   5- "compatible" value : one of
   6        "arm,vexpress-volt"
   7        "arm,vexpress-amp"
   8        "arm,vexpress-temp"
   9        "arm,vexpress-power"
  10        "arm,vexpress-energy"
  11- "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
  12  (see Documentation/devicetree/bindings/arm/vexpress-sysreg.txt
  13  for more details)

  15Optional node properties:
  16- label : string describing the monitored value
  17
  18Example:
  19        energy@0 {
  20                compatible = "arm,vexpress-energy";
  21                arm,vexpress-sysreg,func = <13 0>;
  22                label = "A15 Jcore";
  23        };
