Yes all chips from  AD7606 series (including AD7606B, AD7606C(-16,-18), AD7605-4, AD7606 (-4,-8,-6), AD7607, AD7608, AD7609), as well as AD7616 have a VDrive pin, as well as a RefSelect + RefIn/RefOut pin that takes an input voltage in case RefSelect is high, or outputs the internal reference voltage if RefSelect is low. > >> Signed-off-by: Guillaume Stols >> --- >> Documentation/devicetree/bindings/iio/adc/adi,ad7606.yaml | 9 +++++++++ >> 1 file changed, 9 insertions(+) >> >> diff --git a/Documentation/devicetree/bindings/iio/adc/adi,ad7606.yaml b/Documentation/devicetree/bindings/iio/adc/adi,ad7606.yaml >> index 80866940123c..e480c9a7c7ca 100644 >> --- a/Documentation/devicetree/bindings/iio/adc/adi,ad7606.yaml >> +++ b/Documentation/devicetree/bindings/iio/adc/adi,ad7606.yaml >> @@ -35,6 +35,15 @@ properties: >> >> avcc-supply: true >> >> + vdrive-supply: >> + description: >> + Determines the voltage level at which the interface logic pins will >> + operate. >> + >> + refin-supply: >> + description: >> + The voltage supply for optional external reference voltage. >> + >> interrupts: >> description: >> The BUSY pin falling edge indicates that the conversion is over, and thus >> >> -- >> 2.34.1 >>
