-Description
------------
-
-The Freescale MC13783 and MC13892 are Power Management and Audio Circuits.
-Among other things they contain a 10-bit A/D converter. The converter has 16
-(MC13783) resp. 12 (MC13892) channels which can be used in different modes. The
-A/D converter has a resolution of 2.25mV.
-
-Some channels can be used as General Purpose inputs or in a dedicated mode with
-a chip internal scaling applied .
-
-Currently the driver only supports the Application Supply channel (BP / BPSNS),
-the General Purpose inputs and touchscreen.
-
-See the following tables for the meaning of the different channels and their
-chip internal scaling:
