13description: |
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.
