As a result some ADC related 15 settings are specified in the parent node. 16 The node should be a child node of the stmpe node to which it belongs. 17 18properties: 19 compatible: 20 const: st,stmpe-adc 21 22 st,norequest-mask: 23 $ref: /schemas/types.yaml#/definitions/uint32 24 description: 25 Bitmask specifying which ADC channels should _not_ be 26 requestable due to different usage (e.g. touch). 27 28 "#io-channel-cells": 29 const: 1 30 31required: 32 - compatible 33 34additionalProperties: false 35 36examples: 37 - | 38 stmpe { 39 stmpe_adc { 40 compatible = "st,stmpe-adc"; 41 st,norequest-mask = <0x0F>; /* dont use ADC CH3-0 */ 42 }; 43 }; 44... 45
