+Versatile Express hwmon sensors
+-------------------------------
+
+Requires node properties:
+- "compatible" value : one of
+        "arm,vexpress-volt"
+        "arm,vexpress-amp"
+        "arm,vexpress-temp"
+        "arm,vexpress-power"
+        "arm,vexpress-energy"
+- "arm,vexpress-sysreg,func" when controlled via vexpress-sysreg
+  (see Documentation/devicetree/bindings/arm/vexpress-sysreg.txt
+  for more details)
+
+Optional node properties:
+- label : string describing the monitored value
+
+Example:
+        energy@0 {
+                compatible = "arm,vexpress-energy";
+                arm,vexpress-sysreg,func = <13 0>;
+                label = "A15 Jcore";
+        };
