+Kernel driver twl4030-madc
+=========================
+
+Supported chips:
+        * Texas Instruments TWL4030

+Description
+-----------
+
+The Texas Instruments TWL4030 is a Power Management and Audio Circuit. Among
+other things it contains a 10-bit A/D converter MADC. The converter has 16
+channels which can be used in different modes.
+
+
+See this table for the meaning of the different channels

+The Sysfs nodes will represent the voltage in the units of mV,
+the temperature channel shows the converted temperature in
+degree celcius. The Battery charging current channel represents
+battery charging current in mA.
