title: Mediatek AUXADC - ADC on Mediatek mobile SoC (mt65xx/mt81xx/mt27xx)

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.
