dt-bindings:iio:adc:st,stmpe-adc yaml conversion 



Conversion from freeform text to yaml.
One oddity in this binding is that, for historical reasons it requires
the node name to be stmpe_adc.  I've put that in the decription field
but I'm not sure if there is a better way to specify this?

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 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

      Bitmask specifying which ADC channels should _not_ be

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

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 */

	};
