28 | The Freescale MC13783 and MC13892 are Power Management and Audio Circuits. |
29 | Among 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 | |
31 | A/D converter has a resolution of 2.25mV. | |

33 | Some channels can be used as General Purpose inputs or in a dedicated mode with |
34 | a chip internal scaling applied . | |

36 | Currently the driver only supports the Application Supply channel (BP / BPSNS), |
37 | the General Purpose inputs and touchscreen. | |
