From 81d289c21e395fed9baa1238d300bb1448da6a8d Mon Sep 17 00:00:00 2001 From: Jonathan Santos Date: Wed, 11 Jun 2025 08:50:01 -0300 Subject: [PATCH] dt-bindings: iio: adc: ad7768-1: document regulator provider property The AD7768-1 provides a buffered common-mode voltage output on the VCM pin that can be used to bias analog input signals. Add regulators property to enable the use of the VCM output, referenced here as vcm-output, by any other device.
