      The component uses an external oscillator (osc) if an external oscillator

43
      is connected to its clock pins. Otherwise, it uses an internal reference

44
      clock.

      The first cell is the channel type (dt-bindings/iio/adc/gehc,pmc-adc.h

54
      defines these values):

55
       - 0: voltage

56
       - 1: current

57
      The second cell is the channel number from 0 to 15.
