+********************************
+* Average sample configuration *
+********************************
+
+Devices allowing for reading {in,power,curr,temp}_average values may export
+attributes for controlling number of samples used to compute average.
+
+samples Sets number of average samples for all types of measurements.
+ RW
+
+in_samples
+power_samples
+curr_samples
+temp_samples Sets number of average samples for specific type of measurements.
+ Note that on some devices it won't be possible to set all of them
+ to different values so changing one might also change some others.
