|
|
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.
