What do you need the io-channel-ranges for?
I.e. according to the documenation it is meant for when the adc is also
a "bus node" and has children that should inherit channels from it.
In all saradc uses so far we only have separate nodes referencing the
adc controller (like adc-keys etc), so this does not look like it is needed?
