hwmon: Versatile Express hwmon driver
hwmon framework driver for Versatile Express sensors, providing information about board level voltage (only when regulator driver is not configured), currents, temperature and power/energy usage. Labels for the values can be defined as DT properties. Signed-off-by: Pawel Moll <pawel.moll@arm.com> Acked-by: Guenter Roeck <linux@roeck-us.net>

+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";
+ };
