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. |
