0013 description: |
0014 The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
0015 in some Mediatek SoCs which among other things measures the temperatures
0016 in the SoC. It can be used directly with register accesses, but it is also
0017 used by thermal controller which reads the temperatures from the AUXADC
0018 directly via its own bus interface. See mediatek-thermal bindings
0019 for the Thermal Controller which holds a phandle to the AUXADC.
