| 13 | description: | |
| 14 | The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found |
| 15 | in some Mediatek SoCs which among other things measures the temperatures |
| 16 | in the SoC. 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. |
