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 name myst be stmpe_adc and should be a child node of the stmpe node

  to which it belongs.

properties:

  compatible:

    const: st,stmpe-adc

STMPE ADC driver

----------------

Required properties:

 - compatible: "st,stmpe-adc"

Optional properties:

Note that the ADC is shared with the STMPE touchscreen. ADC related settings

have to be done in the mfd.

- st,norequest-mask: bitmask specifying which ADC channels should _not_ be

  requestable due to different usage (e.g. touch)

Node name must be stmpe_adc and should be child node of stmpe node to

which it belongs.

Example:

	stmpe_adc {

		compatible = "st,stmpe-adc";

		st,norequest-mask = <0x0F>; /* dont use ADC CH3-0 */

	};
