title: ADC on an STMPE multifunction device.
maintainers:
- Stefan Agner <stefan@agner.ch>
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.
properties:
compatible:
const: st,stmpe-adc

Bitmask specifying which ADC channels should _not_ be
requestable due to different usage (e.g. touch).
