25Description
26-----------
27
28The Freescale MC13783 and MC13892 are Power Management and Audio Circuits.
29Among other things they contain a 10-bit A/D converter. The converter has 16
30(MC13783) resp. 12 (MC13892) channels which can be used in different modes. The
31A/D converter has a resolution of 2.25mV.
32
33Some channels can be used as General Purpose inputs or in a dedicated mode with
34a chip internal scaling applied .
35
36Currently the driver only supports the Application Supply channel (BP / BPSNS),
37the General Purpose inputs and touchscreen.
