title: ADC on an STMPE multifunction device.

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 should be a child node of the stmpe node to which it belongs.
