[PATCH v2 3/8] dt-bindings: iio: adc: Add burn-out current properties

From: David Lechner

Date: Thu Jun 25 2026 - 17:57:06 EST


From: Kurt Borja <kuurtb@xxxxxxxxx>

Some ADCs incorporate burn-out current sources that provide current to
the channel's input pins for open-circuit or short-circuit detection.
