[PATCH 03/22] dt-bindings: iio: dac: ad5696: rework on power supplies

Rodrigo Alencar via B4 Relay

From: Rodrigo Alencar <rodrigo.alencar@analog.com>

Add supplies for VDD, VLOGIC and VREF input voltage pins. The vcc-supply
property is deprecated. Certain devices require vref-supply to be
available once an internal reference voltage is absent. Still, this patch
does not add those as 'required' so that the ABI is not broken.
