| description: |
| This ADC forms part of an ST microelectronics STMPE multifunction device . |
| The ADC is shared with the STMPE touchscreen. As a result some ADC related |
| settings are specified in the parent node. |
| The node name myst be stmpe_adc and should be a child node of the stmpe node |
| to which it belongs. |
