Subject: [PATCH v5 1/3] dt-bindings:iio:adc: add generic settling-time-us and oversampling-ratio channel properties
Settling time and over sampling is a typical challenge for different IIO ADC
devices. So, introduce channel specific settling-time-us and oversampling-ratio
properties to cover this use case.
