  685. sigma-delta ADC. The hardware supports calibrated results for
  686. conversion requests and clients include reading voltage phone
  687. power, on board system thermistors connected to the PMIC ADC,
  688. PMIC die temperature, charger temperature, battery current, USB voltage
  689. input, voltage signals connected to supported PMIC GPIO inputs. The
  690. hardware supports internal pull-up for thermistors and can choose between
