1 | MediaTek AUXADC | ||
2 | =============== | ||
3 | |||
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. | ||
11 | |||
12 | Required properties: | ||
13 | - compatible: Must be "mediatek,mt8173-auxadc" | ||
14 | - reg: Address range of the AUXADC unit | ||
15 | |||
16 | Example: | ||
17 | |||
18 | auxadc: auxadc@11001000 { | ||
19 | compatible = "mediatek,mt8173-auxadc"; | ||
20 | reg = <0 0x11001000 0 0x1000>; | ||
21 | }; | ||
