+	  The TWL4030 Monitoring ADC driver enables the host
+	  processor to monitor analog signals using analog-to-digital
+	  conversions on the input source. TWL4030 MADC provides the
+	  following features:
+	   - Single 10-bit ADC with successive approximation register (SAR) conversion;
+	   - Analog multiplexer for 16 inputs;
+	   - Seven (of the 16) inputs are freely available;
+	   - Battery voltage monitoring;
+	   - Concurrent conversion request management;
+	   - Interrupt signal to Primary Interrupt Handler;
+	   - Averaging feature;
+	   - Selective enable/disable of the averaging feature.
+
+	  Say 'y' here to statically link this module into the kernel or 'm'
+	  to build it as a dinamically loadable module. The module will be
+	  called twl4030-madc.ko
