All other ADC properties are valid. Here I was trying to add some
properties for each the channel (ADC channel) used by user on this ADC.
The channel could be single ended (Channel to ground) or 
"diff-channels" where I need to know the pins/channel used.
Maybe I'm missing something but I was trying to follow the binding
from: Documentation/devicetree/bindings/iio/adc/adi,ad7292.yaml


Best regards,
