+                                 The value corresponds to the number of

+       ti,chan-step-avg: Number of averages to be performed for each
+                         channel of ADC. If average is 16 then input
+                         is sampled 16 times and averaged to get more
+                         accurate value. This increases the time taken
+                         by ADC to generate a sample. Valid range is 0
+                         average to 16 averages. Maximum value is 16.
