|
The component uses an external oscillator (osc) if an external oscillator
|
|
is connected to its clock pins. Otherwise, it uses an internal reference
|
|
clock.

The first cell is the channel type (dt-bindings/iio/adc/gehc,pmc-adc.h
|
|
defines these values):
|
|
- 0: voltage
|
|
- 1: current
|
|
The second cell is the channel number from 0 to 15.
