Subject: [PATCH v3 5/6] dt-bindings: mfd: da9062: add regulator gpio enable/disable documentation
Date: Fri, 29 Nov 2019 18:25:36 +0100
Message-ID: <20191129172537.31410-6-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20191129172537.31410-1-m.felsch@pengutronix.de>

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.
