From c6dab7245604862d86f0b6d764919f470584d24f Mon Sep 17 00:00:00 2001 From: Fabrizio Lamarque fl.scratchpad@gmail.com Date: Tue, 30 May 2023 09:53:10 +0200 Subject: [PATCH] dt-bindings: iio: ad7192: Add mandatory reference voltage source

Add required reference voltage (VRef) supply regulator.

AD7192 requires three independent voltage sources: DVdd, AVdd and VRef (on REFINx pin pairs).
