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.
