| * Mediatek AUXADC - Analog to Digital Converter on Mediatek mobile soc (mt65xx/mt81xx/mt27xx) |
| =============== |
| |
| The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found |
| in some Mediatek SoCs which among other things measures the temperatures |
| in the SoC. It can be used directly with register accesses, but it is also |
| used by thermal controller which reads the temperatures from the AUXADC |
| directly via its own bus interface. See |
| Documentation/devicetree/bindings/thermal/mediatek-thermal.txt |
| for the Thermal Controller which holds a phandle to the AUXADC. |
| |
| Required properties: |
| - compatible: Should be one of: |
| - "mediatek,mt2701-auxadc": For MT2701 family of SoCs |
| - "mediatek,mt7622-auxadc": For MT7622 family of SoCs |
| - "mediatek,mt8173-auxadc": For MT8173 family of SoCs |
| - reg: Address range of the AUXADC unit. |
| - clocks: Should contain a clock specifier for each entry in clock-names |
| - clock-names: Should contain "main". |
| - #io-channel-cells: Should be 1, see ../iio-bindings.txt |
| |
| Example: |
| |
| auxadc: adc@11001000 { |
| compatible = "mediatek,mt2701-auxadc"; |
| reg = <0 0x11001000 0 0x1000>; |
| clocks = <&pericfg CLK_PERI_AUXADC>; |
| clock-names = "main"; |
| #io-channel-cells = <1>; |
| }; |
