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?
Sorry, I just copied it from the downstream dts. After checked with David, he suggested that we could remove it.
