1 * Mediatek AUXADC - Analog to Digital Converter on Mediatek mobile soc (mt65xx/mt81xx/mt27xx)
4 The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
5 in some Mediatek SoCs which among other things measures the temperatures
6 in the SoC. It can be used directly with register accesses, but it is also
7 used by thermal controller which reads the temperatures from the AUXADC
8 directly via its own bus interface. See
9 Documentation/devicetree/bindings/thermal/mediatek-thermal.txt
10 for the Thermal Controller which holds a phandle to the AUXADC.
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,mt6765-auxadc": For MT6765 family of SoCs
17 - "mediatek,mt7622-auxadc": For MT7622 family of SoCs
18 - "mediatek,mt8173-auxadc": For MT8173 family of SoCs
19 - "mediatek,mt8183-auxadc", "mediatek,mt8173-auxadc": For MT8183 family of SoCs
20 - reg: Address range of the AUXADC unit.
21 - clocks: Should contain a clock specifier for each entry in clock-names
22 - clock-names: Should contain "main".
23 - #io-channel-cells: Should be 1, see ../iio-bindings.txt
