[PATCH] dt-bindings: iio: Add dedicated CM32181 schema
From: "Rob Herring (Arm)" <robh@kernel.org>

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.
