Subject: [PATCH v2 7/9] ARM: dts: imx7-colibri: specify backlight GPIO
Date: Sun, 17 Dec 2017 21:37:21 +0100 [thread overview]
Message-ID: <20171217203723.15896-7-stefan@agner.ch> (raw)
In-Reply-To: <20171217203723.15896-1-stefan@agner.ch>
The Colibri standard defines SODIMM 71 as backlight enable
GPIO. Assign the GPIO to the backlight node in the module
level device tree.
