1* Mediatek AUXADC - Analog to Digital Converter on Mediatek mobile soc (mt65xx/mt81xx/mt27xx) 2=============== 3 4The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found 5in some Mediatek SoCs which among other things measures the temperatures 6in the SoC. It can be used directly with register accesses, but it is also 7used by thermal controller which reads the temperatures from the AUXADC 8directly via its own bus interface. See 9Documentation/devicetree/bindings/thermal/mediatek-thermal.txt 10for the Thermal Controller which holds a phandle to the AUXADC. 11 12Required properties: 13 - compatible: Should be one of: 14 - "mediatek,mt2701-auxadc": For MT2701 family of SoCs 15 - "mediatek,mt2712-auxadc": For MT2712 family of SoCs 16 - "mediatek,mt7622-auxadc": For MT7622 family of SoCs 17 - "mediatek,mt8173-auxadc": For MT8173 family of SoCs 18 - reg: Address range of the AUXADC unit. 19 - clocks: Should contain a clock specifier for each entry in clock-names 20 - clock-names: Should contain "main". 21 - #io-channel-cells: Should be 1, see ../iio-bindings.txt 22 23Example: 24 25auxadc: adc@11001000 { 26 compatible = "mediatek,mt2701-auxadc"; 27 reg = <0 0x11001000 0 0x1000>; 28 clocks = <&pericfg CLK_PERI_AUXADC>; 29 clock-names = "main"; 30 #io-channel-cells = <1>; 31}; 32
