| description: | |
| 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 mediatek-thermal bindings |
| for the Thermal Controller which holds a phandle to the AUXADC. |
