Subject: [PATCH v2 07/12] backlight: register dependency parser for firmware nodes
Date: Wed, 1 Jul 2015 11:41:02 +0200 [thread overview]
Message-ID: <1435743667-11987-8-git-send-email-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <1435743667-11987-1-git-send-email-tomeu.vizoso@collabora.com>
So others can find out what depends on backlight devices, as specified
in bindings/video/backlight/backlight.txt.
