Subject: [PATCH v2 4/5] dt-bindings: mfd: da9062: add regulator gpio enable/disable documentation
Date:   Wed, 27 Nov 2019 14:59:31 +0100

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.
