Subject: [PATCH 3/5] dt: bindings: lp8860: Add trigger binding to the lp8860
Date: Mon, 4 Dec 2017 15:20:24 -0600 [thread overview]
Message-ID: <20171204212026.14214-4-dmurphy@ti.com> (raw)
In-Reply-To: <20171204212026.14214-1-dmurphy@ti.com>
Add a default trigger optional node to the child node.
This will allow the driver to set the trigger for a backlight.
