[PATCH v2 4/5] dt-bindings: mfd: da9062: add regulator gpio enable/disable documentation

From: Marco Felsch
Date: Wed Nov 27 2019 - 08:59:42 EST


At the gpio-based regulator enable/disable documentation. This property
can be applied to each subnode within the 'regulators' node so each
regulator can be configured differently.
