It can be used directly with register accesses, but it is also 17 used by thermal controller which reads the temperatures from the AUXADC 18 directly via its own bus interface. See mediatek-thermal bindings 19 for the Thermal Controller which holds a phandle to the AUXADC. 20 21properties: 22 compatible: 23 oneOf: 24 - enum: 25 - mediatek,mt2701-auxadc 26 - mediatek,mt2712-auxadc 27 - mediatek,mt6765-auxadc 28 - mediatek,mt7622-auxadc 29 - mediatek,mt8173-auxadc 30 - items: 31 - enum: 32 - mediatek,mt7623-auxadc 33 - const: mediatek,mt2701-auxadc 34 - items: 35 - enum: 36 - mediatek,mt8183-auxadc 37 - mediatek,mt8195-auxadc 38 - mediatek,mt8516-auxadc 39 - const: mediatek,mt8173-auxadc 40 41 reg: 42 maxItems: 1 43 44 clocks: 45 maxItems: 1 46 47 clock-names: 48 const: main 49 50 "#io-channel-cells": 51 const: 1 52 53additionalProperties: false 54 55required: 56 - compatible 57 - reg 58 - clocks 59 - clock-names 60 - "#io-channel-cells" 61 62examples: 63 - | 64 #include <dt-bindings/clock/mt8183-clk.h> 65 soc { 66 #address-cells = <2>; 67 #size-cells = <2>; 68 69 adc@11001000 { 70 compatible = "mediatek,mt8183-auxadc", 71 "mediatek,mt8173-auxadc"; 72 reg = <0 0x11001000 0 0x1000>; 73 clocks = <&infracfg CLK_INFRA_AUXADC>; 74 clock-names = "main"; 75 #io-channel-cells = <1>; 76 }; 77 }; 78... 79
