0012 description:
0013 This ADC forms part of an ST microelectronics STMPE multifunction device .
0014 The ADC is shared with the STMPE touchscreen. As a result some ADC related
0015 settings are specified in the parent node.
0016 The node name myst be stmpe_adc and should be a child node of the stmpe node
0017 to which it belongs.
