[PATCH] dt-bindings: iio: Add dedicated CM32181 schema

From: Rob Herring (Arm)

Date: Mon Sep 21 2026 - 19:38:58 EST


Add a dedicated Capella CM32181 ambient light sensor schema. The device
has optional vdd-supply and interrupt properties, so it no longer fits
in trivial-devices. Include both optional properties in the binding
example.
