As a result some ADC related 15 settings are specified in the parent node. 16 The node name myst be stmpe_adc and should be a child node of the stmpe node 17 to which it belongs. 18 19properties: 20 compatible: 21 const: st,stmpe-adc 22 23 st,norequest-mask: 24 $ref: /schemas/types.yaml#/definitions/uint32 25 description: 26 Bitmask specifying which ADC channels should _not_ be 27 requestable due to different usage (e.g. touch). 28 29 "#io-channel-cells": 30 const: 1 31 32required: 33 - compatible 34 35additionalProperties: false 36 37examples: 38 - | 39 stmpe { 40 stmpe_adc { 41 compatible = "st,stmpe-adc"; 42 st,norequest-mask = <0x0F>; /* dont use ADC CH3-0 */ 43 }; 44 }; 45... 46
