+Description:
+		Write 1 to trigger a calibration of the calibbias or
+		calibscale. For calibscale, a full scale capacitance should
+		be connected to the capacitance input and a
+		calibscale_calibration then started.  For calibbias see
+		the device datasheet section on "capacitive system offset
+		calibration".
