Subject: dt-bindings: iio: ad7192: Add mandatory reference voltage source
From: Fabrizio Lamarque <fl.scratchpad@xxxxxxxxx>
commit c6dab7245604862d86f0b6d764919f470584d24f upstream.
Add required reference voltage (VRef) supply regulator.
AD7192 requires three independent voltage sources: DVdd, AVdd and VRef
(on REFINx pin pairs).
