Description
-----------
-The Freescale MC13783 is a Power Management and Audio Circuit. Among
-other things it contains a 10-bit A/D converter. The converter has 16
-channels which can be used in different modes.
-The A/D converter has a resolution of 2.25mV. Channels 0-4 have
-a dedicated meaning with chip internal scaling applied. Channels 5-7
-can be used as general purpose inputs or alternatively in a dedicated
-mode. Channels 12-15 are occupied by the touchscreen if it's active.

+Description
+-----------
+
+This driver implements support for the Microchip Technology MCP3021 chip.
+
+The Microchip Technology Inc. MCP3021 is a successive approximation A/D
+converter (ADC) with 10-bit resolution.
+This device provides one single-ended input with very low power consumption.
+Communication to the MCP3021 is performed using a 2-wire I2C compatible
+interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are available.
+The default I2C device address is 0x4d (contact the Microchip factory for
+additional address options).
