The generic IIO channel bindings is also introduced here to provide this feature. The legacy channel binding is kept for backward compatibility. Changes in v2: - Add 'deprecated' to channels legacy properties in ADC bindings - Add set/clr service for common registers, to make code more generic in internal channels enable/disable services. - Expose vrefint channel as a processed channel to return the actual value of vrefp. - Minor code improvements Changes in v3: - fix vrefint sampling time check.
